What is a homozygous dominant genotype?

Understand the Problem

The question is asking for an explanation of what a homozygous dominant genotype is. This concept relates to genetics and refers to an organism that has two identical dominant alleles for a particular gene.

Answer

A genotype with two identical dominant alleles.

A homozygous dominant genotype consists of two identical dominant alleles for a given trait.

Answer for screen readers

A homozygous dominant genotype consists of two identical dominant alleles for a given trait.

More Information

In a homozygous dominant genotype, each parent contributes a dominant allele, hence the individual possesses two dominant alleles (for example, 'AA' for a gene). This typically results in the expression of the dominant trait.

Tips

A common mistake is to confuse 'homozygous dominant' with 'heterozygous,' where the individual has one dominant and one recessive allele.
