Which genotype shows the heterozygous condition?
When a gene pair (allele) contains two different genes in an organism then the organism is considered as heterozygous for that particular character. In the given options ‘ Rr ‘ shows heterozygous condition.
Is the genotype DD heterozygous?
Susan’s genotype is “Dd”, so she is considered HETEROZYGOUS (has two different alleles for a specific gene). Although Susan has both the allele “D” to make dimples and the allele “d” in her genotype, her phenotype is the presence of dimples.
What is homozygous and heterozygous condition?
Homozygous is a genetic condition where an individual inherits the same alleles of a gene from both the parents. Heterozygous is a genetic condition where an individual inherits different alleles of a gene from the two parents.
What is heterozygous and homozygous?
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.
What is genotype 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. In contrast, the term “heterozygous” is used to describe the allelic pair, “Aa”.
What is genotype BB?
An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb.
What genotype is EE?
The person with the Ee genotype is heterozygous for the trait, in this case, free earlobes. An individual is heterozygous for a trait when it has two different allelic forms of a particular gene. The heterozygous individual received one form of the gene from one parent and a different allele from the other parent.
What is the genotype of RR?
The (RR) genotype is homozygous dominant and the (rr) genotype is homozygous recessive for seed shape. In the image above, a monohybrid cross is performed between plants that are heterozygous for round seed shape. The predicted inheritance pattern of the offspring results in a 1:2:1 ratio of the genotype.
What are homozygous and heterozygous condition states examples?
Individuals carrying two identical alleles (RR or rr) are known as homozygous. While individual organisms bearing different alleles (Rr) are known as heterozygous. For example, assume gene of hair colour has two alleles, one of the allele codes for brown (R) and the other codes for black (r).
How do you find the homozygous genotype?
You inherit two alleles for each gene. One comes from your biological mother and one comes from your biological father. If the alleles are identical, you’re homozygous for that specific gene. For instance, it could mean you have two alleles for the gene that causes brown eyes.
What is genotype example?
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.
Which of the following genotypes are homozygous?
A homozygous genotype means that you have two of the same alleles, which are represented by the letters A or a. So if an individual has AA or aa, we say they are homozygous. If that have Aa, they are heterozyous.
