Question

which of these genotypes represent a homozygous recessive trait?
○ tt
○ tt
○ tt

Explanation:

To determine a homozygous recessive genotype, we recall: Homozygous means two identical alleles, and recessive alleles are typically represented by lowercase letters.

• \( Tt \) is heterozygous (one dominant, one recessive allele).
• \( tt \) has two identical recessive alleles (homozygous recessive).
• \( TT \) has two identical dominant alleles (homozygous dominant).

Answer:

B. tt (assuming the options are labeled as: A. Tt, B. tt, C. TT)
