Punnett Squares
1. In rabbits, coat length is determined by one allele, the G allele. Long coats are
dominant to short coats.
a) diagram a Punnett square to determine the traits of the offspring of a
crossing of a pure bred long coated male with a pure bred short coated
female.
G G
g Gg Gg
g Gg Gg
So, all the offspring would have the genotype “Gg”, meaning they would all have
long coats because the long coat trait is dominant. However, they would also be
carriers of the short coat trait, making them genetic hybrids.
