Question

In guinea pigs, short hair (S) is dominant over long hair (s). A female guinea pig with short hair but whose father had long hair is mated with a male with long hair but whose parents were both shorthaired. Using a Punnett square, predict the genotypic and phenotypic ratios of their offspring.

urgent please help meeee

Answer 1

female's father is long haired so "ss". Female cant be SS because of her father so her genotype is Ss. Male's genotype is ss.

              S     x     s

         s   Ss          ss

         s   Ss          ss

Short haired offspring: 50%

Long haired offspring: 50%
