inheritance 2

A plant with red flowers is crossed with a plant with white flowers. The resulting offspring have pink flowers. What term describes the dominance of this trait?

•     Recessiveness

•     Dominance

•    Incomplete dominance

•    Codominance

Two pure breeding plants are crossed. One plant has red flowers and the other has white flowers.

What phenotype(s) would be seen in the first generation if flower color exhibited incomplete dominance?

• All offspring would have pink flowers

• All offspring would have both red and white flowers

• Half of the offspring would have red flowers, and half would have white

• Half of the offspring would have red flowers, and half would have pink

This type of inheritance pattern is a MIXTURE of both traits.

• incomplete dominance

• co-dominance

• Mendelian dominance

• complete dominance

Incomplete dominance or co-dominance?
A calico cat shows both the traits for orange fur and black fur. 

• Incomplete Dominance

• Co-dominance

• Complete dominance

• Mendelian dominance

A breed of chicken shows incomplete dominance for feather color. One dominant allele codes for black feathers, another dominant allele codes for white feathers. The feathers of heterozygous chickens of this breed will be....

• all black

• all white

• all gray

• speckled black and white

What are the possible genotypes for a person who has the blood group A?

• I^AI^A

• I^AIⁱ

• I^AI^B

• I^BIⁱ

If red (R) and white (r) are codominant alleles that determine flower color, what phenotypes are possible for this gene?

• Red, white, and red-white spotted

• Red, white, and pink

• Pink only

• Red and white

If Tom has the genotype I^AI^B and Angela has the genotype I^BIⁱ, what are the possible phenotypes of their children?

• Group A, Group B, Group AB only

• Group A, Group B, Group AB, and Group O

• Group A and Group AB only

• Group A and Group B only

This type of dominance is ........................... because the heterozygote shows a phenotype that is .............................. .

• co-dominance, blended

• co-dominance, equal

• incomplete dominance, blended

• incomplete dominance, equal

A man with type O blood is accused of being the father of a type B baby. The mother is type A. Could this man be the father?
