Question

Pearl the whale had a horrible accident at cheerleading practice and needed a blood transfusion. So she needed to find out her possible blood type. Her dad, Mr. Krabbs is heterozygous for blood type A and her mom is heterozygous for blood type B. Make a Punnett square to show Pearl’s possible blood type(s). Mr. Krabbs genotype: ________ Mrs. Krabbs genotype: ________ What is the possibility of Pearl having blood type O? ____ What is the possibility of Pearl having blood type AB? ____ What is the possibility of Pearl having blood type A? ____ What is the possibility of Pearl having blood type B? ____ - Is this scenario an example or incomplete dominance or codominance? Explain. - How can some people receive O-type blood which is recessive?

Answer 1

Mr Krabs genotype: A0

Mrs K= B0

Possible genotypes: AB, B0, A0, 00

The possibility that pearl has blood type O is 25%, type A 25%, type B 25%

this scenario is an example of codominance
