Genetics

Multiple choice

• A trait is incompletely dominant. You would expect the phenotype of the offspring to be:

a. A combination of the parents’ phenotypes.

b. The same phenotype as one of the parents.

c. A blend of the parents’ phenotypes.

d. Unlike either parent.

Problem

• Purple is dominant to white in pea plants. Cross a heterozygous purple plant with itself. Give the genotypes and phenotypes.

Problem

• Purple is dominant to white in pea plants. Cross a white pea plant with a homozygous purple pea plant. What are the genotypes and phenotypes.

Multiple choice

• AB blood is an example of:a. Incomplete dominance

b. Codominance

c. Complete dominance

d. Recessive trait

Problem

• A sample of peas contains 300 green peas and 300 yellow peas.– What proportion of peas are green?

– What is the ratio of green to yellow peas?

– What were the genotypes of the parents?

Problem

• Hemophilia is a sex-linked recessive disorder.– Cross a normal male with a carrier female.

What are the chances that they will have a child with hemophilia?

Problem

• What are the possible blood types of children when the mom has O blood and the dad has AB blood?

Problem

• In peas smooth is dominant to wrinkled and green is dominant to yellow. Cross a heterozygous smooth heterozygous green plant with a wrinkled yellow plant.
