Can You Say For Certain What The Genotype Is For The Daughter

Contents

How do you describe a genotype?

A genotype is an individual’s collection of genes. The term also can refer to the two alleles inherited for a particular gene. The genotype is expressed when the information encoded in the genes’ DNA is used to make protein and RNA molecules.

What is an example of a genotype?

Genotype examples

A gene encodes eye color. … If the child inherits two different alleles (heterozygous) then they will have brown eyes. For the child to have blue eyes they must be homozygous for the blue eye allele.

What are the 3 types of genotypes?

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

What genotype are you if you do not have hemophilia?

When the offspring do not have a X^H and only have the X^h allele/alleles they will have the hemophilia condition. Man’s genotype is X^hY. Daughter’s genotype is X^HX^h (She got the X^h from her father. She has a normal phenotype so we know her other allele is X^H.
…

	X^B	X^b
Y	X^BY	X^bY

What is the AA genotype?

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. In contrast the term “heterozygous” is used to describe the allelic pair “Aa”.

How do you determine the genotype of a parent?

To construct a Punnett square the genotypes of both parents must be known. One parent’s alleles are listed across the top of the table and the other parent’s alleles are listed down the left hand side. The resulting offspring genotypes are produced at the intersection of the parent’s alleles.

What are 5 examples of genotype?

Examples of Genotype:

Height. For an individual’s gene makeup there is tall variety (T) and there is short variety (s). T and s are called the alleles. …
Freckles or no freckles. Again the information that is passed from parent to child is carried in the cell of the genotype. …
Lactose intolerance.

What are the genotypes of the offspring?

An offspring’s genotype is the result of the combination of genes in the sex cells or gametes (sperm and ova) that came together in its conception. One sex cell came from each parent. Sex cells normally only have one copy of the gene for each trait (e.g. one copy of the Y or G form of the gene in the example above).

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 is the father’s genotype?

Potential blood types of father

Mother’s Blood Type	Possible Mother’s Genotype	Possible Father’s Genotype
A	AA AO	AA AO
A	AA AO	AB
A	AA AO	BB BO
A	AA AO	OO

What is the genotype of the woman?

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 are the genotypes for gender?

Most people have either two X chromosomes (genotypic female) or an X and a Y chromosome (genotypic male). Phenotypic sex refers to an individual’s sex as determined by their internal and external genitalia expression of secondary sex characteristics and behavior.

What genotypes would the parents have to be to have a child with hemophilia?

The father’s sex chromosomes are labeled XY with the X chromosome carrying the hemophilia gene. The father only passes half of his sex chromosomes to the baby either the X or the Y. If the baby gets the Y chromosome from the father it will be a boy.

What is the genotype of a female with hemophilia?

Females having one normal and one abnormal gene are asymptomatic carriers and will transmit the abnormal gene on average to one half of their sons and one half of their daughters.
…
Expression and Transmission.

Phenotype	Genotype
Carrier female	XhXH
Affected female	XhXh

What allele combination would a daughter inherit to be colorblind?

One example of an X-linked trait is red-green colorblindness. Let (X^c) represent the recessive allele that causes colorblindness and (X⁺) represent the normal dominant allele. Females that are X⁺X⁺ or X⁺X^c have normal color vision while X^cX^c females are colorblind.

Can genotype AS and AA get married?

If AA marries an AS. They can have kids with AA and AS which is good. In some cases all the kids will be AA or all the kids may be AS which limits their choice of a partner. AS and AS should not get married there is the risk of having children with SS.

What is the best genotype?

Health Tips

Types of Genotype. The genotypes in humans are AA AS AC SS. They refer to the hemoglobin gene constituents on the red blood cells. …
Compatible genotypes for marriage are: AA marries an AA. That’s the best compatible. …
Solution. The only thing that can change the genotype is the bone marrow transplant (BMT).

What does AA AS and SS means?

High-resolution image analysis was employed in the analysis of round (discoid) erythrocytes from hematologically normal (AA) individuals AA individuals with nonspecific anemia individuals with sickle cell trait (AS) individuals with SC disease (SC) and individuals with sickle cell anemia (SS).

What is the genotype of the mother and father?

Scientists use the term genotype to refer to the combination of mother and father genes in the person’s make up. AA AO and OO are the 3 genotypes that may result from the mating of the parents in the example above. Scientists use the term phenotype to refer to what gene is actually expressed.

What are the genotypes of the F2 generation?

F2 tall red plants will have 4 genotypes i.e. homozygous tall homozygous red (TTRR) homozygous tall heterozygous red (TTRr) heterozygous tall and homozygous red (TtRR) and heterozygous tall and heterozygous red (TtRr) will be in the ratio of 1:2:2:4.

What are the genotypes of the parents in the Monohybrid cross?

For a monohybrid cross of two true-breeding parents each parent contributes one type of allele. In this case only one genotype is possible. All offspring are Yy and have yellow seeds. … Therefore the offspring can potentially have one of four allele combinations: YY Yy yY or yy.

Can As marry as?

However AS and AS should not marry because there is every chance of having a child with Sickle Cell Disease while AS and SS shouldn’t think of marrying. And definitely SS and SS must not marry since there’s absolutely no chance of escaping having a child with the sickle cell disease.

How many possible genotypes are there among the offspring?

Genotype is also used to refer to the pair of alleles present at a single locus. With alleles ‘A’ and ‘a’ there are three possible genotypes AA Aa and aa. With three alleles 1 2 3 there are six possible genotypes: 11 12 13 22 23 33. First we must appreciate that genes do not act in isolation.

What is Punnett square in genetics?

The Punnett square is a table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are given. In its simplest form the Punnett square consists of a square divided into four quadrants.

What is the genotype of a female with normal vision?

Problem 1: Audrei’s genotype

Female Genotype	Female Phenotype
X^R X^R	Normal Vision
X^R X^r	Normal vision “carrier”
X^r X^r	Red-green color blind

Is YY genotype possible?

The types of gametes produced by each individual depends on its genotype. So a YY genotype can only produce gametes with Y alleles. An individual with a Yy genotype produces half Y gametes and half y gametes. A yy genotype produces only y gametes.

What is the genotype for a yellow plant?

YY
The dominant seed color is yellow therefore the parental genotypes were YY for the plants with yellow seeds and yy for the plants with green seeds.

What’s genotype and phenotype examples?

Genotypes remain the same throughout the life of the individual. Examples of phenotypes seen in various organisms include the blood group eye color and hair texture as well as genetic diseases in humans pod size and color of leaves beak birds etc.

What are heterozygous twins?

Heterozygous

Heterozygous refers to having inherited different forms of a particular gene from each parent. A heterozygous genotype stands in contrast to a homozygous genotype where an individual inherits identical forms of a particular gene from each parent.

Does parents blood group decide baby’s blood group?

Just like eye or hair color our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example if an O gene is paired with an A gene the blood type will be A.
