Since pink bodies are from a dominant gene and yellow are from a recessive gene, the change of them having pink child is 75%, and a yellow child is 25%. Pink bodies are classified with an uppercase letter “P” and a lowercase “p”, making is heterozygous. It’s dominant, but still carries the possibility for the recessive gene to come through. As long as the genotype is classified with at least one uppercase letter, it’s automatically a dominant gene. After following the Punnett square, you’ll find:
Pink: 75%
Yellow: 25%
Each square (there’s 4) is worth 25% (so when added up, it totals to be 100%).
