SS and Ss ? Sorry if that wasn’t even correct but i used a punnet square thing and i haven’t done this in 2 or 3 years

Answer:

The possible genotype for offspring offspring of a carrier (Ss) and a person who lacks the sickle-cell is allele (SS) are: SS and Ss

Types of gametes produced by carrier parent: S and s

Types of gametes produced by normal parent: S

The offspring produced by this cross can have two types of genotypes: SS and Ss.

The same is shown with the hep of Punnett square below.
