Question

if an individual has two recessive alleles for the same trait, the individual is said to be
haploid for the trait.
heterozygous for the trait.
mutated.
homozygous for the trait.

Explanation:

To solve this, we analyze each option:

• "Haploid for the trait" refers to having one set of chromosomes, not related to allele pairs for a trait. Eliminate this.
• "Heterozygous for the trait" means having two different alleles (one dominant, one recessive) for a trait. The question states two recessive alleles, so this is incorrect.
• "Mutated" implies a change in DNA sequence, not related to having two recessive alleles for a trait. Eliminate this.
• "Homozygous for the trait" means having two identical alleles (both recessive here) for a trait. This matches the description.

Answer:

D. homozygous for the trait.
