Practice Problems Flashcards
In guinea pigs, straight hair is dominant to wavy hair. List the possible genotypes and phenotypes of offspring produced from a homozygous wavy hair guinea pig crossed with a heterozygous straight hair guinea pig.
In parrots, blue feathers and yellow feathers show incomplete dominance. In the heterozygous situation, the combination of both colors appears green. What are the possible phenotypes and genotypes of the offspring of two green parrots?
Can two parents that are type AB blood have a type O child? Prove your answer with a punnett square.
Can a type O man be the father of a type B baby if the mother is type A?
A man who has normal blood clotting is married to a woman who is a carrier of hemophilia. What is the chance that they will produce a child with hemophilia? Show a punnett square to prove your answer.
In a certain fish, blue scales (B) and red scales (R) are codominant. When a fish has the genotype BR, it has a patchwork of blue and red scales. What are
the possible phenotypes and genotypes of the offsprings of a BR fish and a fish that only has Blue Scales?
The color of a dog’s fur is controlled by one gene. For that gene, the allele B = black and b = brown. You have a dog with black fur, but do not know whether
that dog’s genotype is BB or Bb. How would you determine the dog’s genotype?
