Question

In llamas, a shaggy coat (S) is dominant over a smooth coat (s). If two hybrid/heterozygous llamas are mated, what are the possible genotypes of their offspring? Select all that apply.
[Hint: you will want to start by writing down the genotypes of the parents, and determining the gametes they can make.]

 

a.) ss
b.) Ss
c.) SsSs
d.) SS

Answer 1

Please make a punnet square:

 

 

Parental genotypes are S/s  for both parents since they are heterzygous.

 

         S            s

 S      SS         Ss

 

 

s       Ss           ss
