1. what is the puppys genotype for the trait of hair length? *

10 points
rr
rr
rr
none of the above

Explanation:

Step1: Identify alleles from parents

From mom, the allele for hair length is \( R \); from dad, it's \( r \).

Step2: Determine puppy's genotype

The puppy inherits one allele from each parent, so the genotype for hair length is \( Rr \).

Answer:

B. Rr (assuming the options are labeled with Rr as one of them; based on the allele inheritance, the correct genotype is Rr)
