Question

which genotype below represents a dihybrid individual?
○ bbee
○ bbee
○ bbee
○ bbee
done

Explanation:

A dihybrid individual has two different pairs of alleles (heterozygous) for two different genes. Let's analyze each option:

• bbee: Homozygous recessive for both genes (bb and ee), so not dihybrid.
• BBee: Homozygous dominant for B and homozygous recessive for e, only one pair is heterozygous? No, BB is homozygous, ee is homozygous. So not dihybrid.
• BbEe: Heterozygous for both B (Bb) and E (Ee) genes. This has two different heterozygous allele pairs, so it's a dihybrid.
• bbEE: Homozygous recessive for B and homozygous dominant for E, both pairs are homozygous. Not dihybrid.

Answer:

C. BbEe
