Question

which of the individuals below would express a recessive trait? bb, bb, bb

Explanation:

In genetics, a recessive trait is expressed when an individual has two recessive alleles (homozygous recessive). For a trait with alleles \( B \) (dominant) and \( b \) (recessive):

• \( BB \) is homozygous dominant, so it expresses the dominant trait.
• \( Bb \) is heterozygous, and the dominant allele \( B \) masks the recessive allele \( b \), so it expresses the dominant trait.
• \( bb \) is homozygous recessive, so it expresses the recessive trait.

Answer:

bb
