which term best describes the genotype bb?

a hybrid
b heterozygous
c homozygous dominant
d homozygous recessive

Explanation:

To determine the term for genotype 'bb', we analyze each option:

• Option a: Hybrid (or heterozygous) has two different alleles (e.g., Bb), so 'bb' is not hybrid.
• Option b: Heterozygous requires two different alleles (e.g., Bb), but 'bb' has two identical alleles, so not heterozygous.
• Option c: Homozygous dominant has two dominant alleles (e.g., BB), while 'bb' has recessive alleles, so not this.
• Option d: Homozygous recessive has two identical recessive alleles, which matches 'bb' (both 'b' are recessive and identical).

Answer:

d. Homozygous Recessive
