Question

patrick is pink and patty is also pink, but they made a blue baby. patricks genotype must be: pp pp pp bb

Explanation:

Step1: Analyze the inheritance pattern

Since Patrick and Patty are pink (dominant trait) but have a blue (recessive trait) baby. Let the dominant allele be \(P\) (pink) and recessive allele be \(p\) (blue). A recessive trait (blue) in the baby means the baby has a genotype of \(pp\). Each parent must contribute one \(p\) allele.

Step2: Determine Patrick's genotype

Patrick is pink (has at least one \(P\) allele) and contributes a \(p\) allele to the baby. So Patrick's genotype must be \(Pp\) (heterozygous).

Answer:

\(Pp\)
