Question
Which of the following is homozygous dominant?
- Jj
- Rr
- MM
- ee
Hint:
The presence of equal alleles at a specific gene locus.
The correct answer is: MM
- Homozygous, as related to genetics, refers to having inherited the same alleles of a genomic marker from each biological parent.
- Thus, an individual who is homozygous for a genomic marker has two identical versions of that marker
- Hence MM is Homozygous dominant.
