Therefore, the possible genotypes of the offspring are 50% RR, Rr 25% , and rr 25%.
The possible genotypes of the offspring are:
Rr, and rr.
The Punnett square will show that each offspring has a 50% chance of inheriting the R allele from one parent and a 50% chance of inheriting the r allele from the other parent. This means that there is a 25% chance of an offspring having the genotype RR (pure black), a 50% chance of having the genotype Rr (heterozygous black), and a 25% chance of having the genotype rr (pure white).
