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 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.
