Is homozygous dominant a genotype or phenotype?

Is heterozygous dominant a genotype or phenotype?

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.

Is homozygous a genotype?

The presence of two identical alleles at a particular gene locus. A homozygous genotype may include two normal alleles or two alleles that have the same variant.

Is genotype a dominant or phenotype?

Dominance affects the phenotype derived from an organism’s genes, but it does not affect the way these genes are inherited. Complete dominance occurs when the heterozygote phenotype is indistinguishable from that of the homozygous parent.

Which of the following is a homozygous dominant genotype?

The correct answer: The genotype which shows the character of homozygous dominant is D. SS.

What is the genotype of the heterozygote?

The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).

Is homozygous dominant or recessive?

Homozygous means that the organism has two copies of the same allele for a gene. An organism can be homozygous dominant, if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele.

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 are dominant phenotypes?

Organisms that reproduce sexually carry genes from each parent. … The genes that are expressed are responsible for your traits, or phenotype. A dominant phenotype is a trait resulting from a dominant gene.

What represents a homozygous genotype?

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.
