What is the genotype of the male answer?

What is a genotype of the male?

Genotypic sex refers specifically to an individual’s two sex chromosomes. Most people have either two X chromosomes (genotypic female) or an X and a Y chromosome (genotypic male).

What is the genotype of the female answer?

Using the definition of “genotype” that refers to a relevant section of the DNA sequence inherited by an organism, the genotype of female humans is XX, as opposed to male humans’ genotype XY.

What is the genotype of the husband?

The genotypes of a husband and wife are IAIB and IAi respectively.

What are the 3 types of genotypes?

There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.

What chromosomes do males have?

Each person normally has one pair of sex chromosomes in each cell. The Y chromosome is present in males, who have one X and one Y chromosome, while females have two X chromosomes.

What is in the Y chromosome?

The Y chromosome contains a “male-determining gene,” the SRY gene, that causes testes to form in the embryo and results in development of external and internal male genitalia. If there is a mutation in the SRY gene, the embryo will develop female genitalia despite having XY chromosomes.

Does XY mean female?

Sex chromosomes usually determine whether you are female or male. Women are XX. Men are XY. However, genetically, a few women are actually men.

What are the genotypes for husband and wife?

The genotypes of a husband and Wife are IAIB and IA i .

What is the genotype for gray fur?

ff: 257. Black fur: 257. Grey fur: 757. Genotypes: EE: 1007.

What blood group will your child be?

Two parents with B blood type will have a baby with either B or O. Two parents with blood type AB will have a baby with either A, B, or AB. Two parents with the O blood type will have a baby with O. One parent with blood type A and one parent with the B blood type might have a baby in any blood group.

What is my genotype?

In a nutshell: your genotype is your complete heritable genetic identity, the sum total of genes transmitted from parent to offspring. There are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon). SS and AC are the abnormal genotypes or the sickle cells.

What is a genotype example?

Genotype examples

A gene encodes eye color. In this example, the allele is either brown, or blue, with one inherited from the mother, and the other inherited from the father. The brown allele is dominant (B), and the blue allele is recessive (b).

What is the chromosome?

(KROH-muh-some) A structure found inside the nucleus of a cell. A chromosome is made up of proteins and DNA organized into genes. Each cell normally contains 23 pairs of chromosomes.

Are males XY or YY?

X and Y chromosomes

Typically, human females have two X chromosomes while males possess an XY pairing. This XY sex-determination system is found in most mammals as well as some reptiles and plants. Whether a person has XX or XY chromosomes is determined when a sperm fertilizes an egg.

Why is there no YY genotype?

Known as nondisjunction, this is an error in the sperm cell’s division. The resulting child will have an extra Y chromosome in every cell of his body. However, it’s not a hereditary trait — fathers with XYY chromosomes don’t pass on this syndrome to their sons.

How do you find XY chromosomes?

The X and Y chromosomes, also known as the sex chromosomes, determine the biological sex of an individual: females inherit an X chromosome from the father for a XX genotype, while males inherit a Y chromosome from the father for a XY genotype (mothers only pass on X chromosomes).

What is XY sperm?

Females have two X chromosomes in their cells, while males have X and Y chromosomes in their cells. Egg cells contain an X chromosome, while sperm cells contain an X or a Y chromosome. This arrangement means that during fertilization, it is the male that determines the sex of the offspring.

Does Y chromosome mean boy?

Biological sex in healthy humans is determined by the presence of the sex chromosomes in the genetic code: two X chromosomes (XX) makes a girl, whereas an X and a Y chromosome (XY) makes a boy.

Can a male have no Y chromosome?

About 1 in 20,000 men has no Y chromosome, instead having 2 Xs. This means that in the United States there are about 7,500 men without a Y chromosome. The equivalent situation – females who have XY instead of XX chromosomes – can occur for a variety of reasons and overall is similar in frequency.

Can XY give birth?

Yes it is possible for someone with a Y chromosome to become pregnant and give birth to a child. But it’s extremely rare. One of the most important requirements for pregnancy is having a uterus. Most people with a Y chromosome don’t have a uterus and without one, there is no place for a baby to grow.

What are the possible genotypes and phenotypes of a cross between IAIA female and IAIB male?

3 genotypes, 4 phenotypes.

What are the possible genotypes and phenotypes of the children if both husband and wife have the blood type AB alleles IAIB?

Therefore, 4 genotypes and 3 phenotypes are possible.

How many different genotype and phenotype are possible?

There are three common alleles in the ABO system. These alleles segregate and assort into six genotypes, as shown in Table 1. As Table 1 indicates, only four phenotypes result from the six possible ABO genotypes.

What is the genotype for the male parent?

The male parent is heterozygous which means he has one allele for black eyes and one allele for red eyes. Since his eyes are black, this means that black allele must be dominant over the red allele. So the male parents genotype is “Bb” (B= allele for black eye, b=allele for red eye).

What is the genotype for the tall plant?

Genotypes for plant height are TT, Tt, tt. … Phenotypes for plant height are tall or short. TT and Tt genotypes both expressed the tall phenotype because the T is dominant to t. Only the tt genotype expressed the short phenotype.

What is a genotype and phenotype?

A phenotype is an individual’s observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.

What blood type is my dad?

Blood Type

Blood Type Mother
Father A B
A A or O AB, A, B or O
B AB, A, B or O B or O
AB AB or A or B AB or A or B

Can O and B have a baby?

An O and B crossing can not produce an A or AB child. An AB with an O can produce A children or B children but not O. In short the ABO system can prove you are not a parent but not that you are, as there are millions of other people with the same blood group.

Where can I find my blood type?

Many people don’t know their blood type. Here’s how to find out yours

  • Ask your parents or doctor.
  • Blood draw.
  • At-home blood test.
  • Blood donation.
  • Saliva test.

Can AA and AA give birth to as?

Compatible genotypes for marriage are:

That way you save your future children the worry about genotype compatibility. AA marries an AS. You’ll end up with kids with AA and AS which is good. But sometimes if you’re not lucky all the kids will be AS which limits their choice of partner.

Can AA and AC marry?

They refer to the hemoglobin gene constituents on the red blood cells. AC is rare, whereas AS and AC are abnormal. The compatible genotypes for marriage are, AA marries an AA — which is the best compatible, and that way, the couple save their future children the worry about genotype compatibility.

What is genotype AS and AA?

If the dominant allele is labeled as “A” and the recessive allele, “a”, three different genotypes are possible: “AA”, “aa”, and “Aa”. The term “homozygous” is used to describe the pairs “AA” and “aa” because the alleles in the pair are the same, i.e. both dominant or both recessive.

What is called genotype?

In a broad sense, the term “genotype” refers to the genetic makeup of an organism, in other words, it describes an organism’s complete set of genes. … Each pair of alleles represents the genotype of a specific gene.

How do you write a genotype?

The genotype is often written as YY or yy, for which each letter represents one of the two alleles in the genotype. The dominant allele is capitalized and the recessive allele is lower case.

What are 46 chromosomes?

46 chromosomes in a human call, arranged in 23 pairs. These 46 chromosomes carry the genetic information that’s passed from parent to child through heredity. It is the very detail of this genetic material – in the DNA – that makes most people (other than identical siblings) totally unique.

What is chromosome Class 9?

Chromosomes are the genetic material present in all cells. They are present in the nucleus of a eukaryotic cell. They are a thread-like structure. Each chromosome of a eukaryotic cell contains DNA and associated proteins, known as histone proteins.

What are the 23 chromosomes?

​Chromosome

Humans have 23 pairs of chromosomes–22 pairs of numbered chromosomes, called autosomes, and one pair of sex chromosomes, X and Y. Each parent contributes one chromosome to each pair so that offspring get half of their chromosomes from their mother and half from their father.
