Monozygous
The Correct Answer is D
A. Heterozygous refers to having two different alleles for a gene, one inherited from each parent.
B. Recessive refers to an allele that only expresses its trait if two copies are present (homozygous), but this term does not describe the inheritance pattern itself.
C. Dominant refers to an allele that expresses its trait even if only one copy is present, but again, this term does not describe the inheritance pattern.
D. Homozygous describes a gene when the same allele is inherited from both parents (e.g., AA or aa).
