Question

multiple answer 1 point select the homozygous recessive genotypes below. select all that apply. bb aa bb aa aa bb

Explanation:

To determine homozygous recessive genotypes, we recall that a homozygous recessive genotype has two identical recessive alleles. Recessive alleles are typically represented by lowercase letters.

• BB: Homozygous dominant (two dominant alleles, uppercase).
• AA: Homozygous dominant (two dominant alleles, uppercase).
• Bb: Heterozygous (one dominant, one recessive allele).
• Aa: Heterozygous (one dominant, one recessive allele).
• aa: Homozygous recessive (two recessive alleles, lowercase).
• bb: Homozygous recessive (two recessive alleles, lowercase).

So the homozygous recessive genotypes are aa and bb.

Answer:

aa, bb
