What is a homozygous dominant genotype?
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.
What are examples of homozygous genotypes?
A homozygous genotype can appear in various ways, such as:
- Eye color. The brown eye color allele is dominant over the blue eye allele.
- Freckles. Freckles are tiny brown spots on the skin.
- Hair color. Red hair is a recessive trait.
What is the difference between a homozygous dominant and a heterozygous genotype?
Homozygous means two copies of the same allele, such as two dominant alleles. Heterozygous means one of each type of allele, one dominant and one recessive.
What does it mean when a genotype is dominant?
= Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.
What is meant by homozygous and heterozygous?
Heterozygous is when different forms of a specific gene are inherited from each parent. Homozygous is when a gene inherited from each parent is identical. Basically, heterozygous means different while homozygous means the same. 4.
What is heterozygous genotype?
Listen to pronunciation. (HEH-teh-roh-ZY-gus JEE-noh-tipe) 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).
What do you mean by homozygous?
(HOH-moh-ZY-gus JEE-noh-tipe) 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.

What do you mean by H * * * * * * * * * and heterozygous?
Homozygous and heterozygous are terms that are used to describe allele pairs. Individuals carrying two identical alleles (RR or rr) are known as homozygous. While individual organisms bearing different alleles (Rr) are known as heterozygous.
What are homozygous and heterozygous alleles?
Homozygous: You inherit the same version of the gene from each parent, so you have two matching genes. Heterozygous: You inherit a different version of a gene from each parent. They do not match.
What is difference between dominant and recessive?
In this case, only the dominant trait will get expressed and the recessive allele will not get expressed….Complete step by step answer:
| Dominance | Recessive |
|---|---|
| The dominant allele is represented in capital letters. | The recessive allele is represented in small letters. |
What does homozygous mean in genetics?
In genetics, homozygous is a term which is used to refer to an organism which has inherited two identical copies of a gene. For example, if a plant is homozygous for red flowers, it means that it has inherited two copies of the gene which tell it to produce red flowers.
