patterns of inheritance

When red snapdragons are crossed with white snapdragons, the offspring produce pink flowers. This is an example of:

• complete dominance

• incomplete dominance

• codominance

• polygenic inheritance

• multiple alleles

When red cows are crossed with white cow, the offspring have a mix of red hair and white hair. These cows are called roan. This is an example of:

• complete dominance

• incomplete dominance

• codominance

• polygenic inheritance

• multiple alleles

The gene for human blood type has three alleles, A, B and O. This is an example of:

• complete dominance

• incomplete dominance

• codominance

• polygenic inheritance

• multiple alleles

This flower is produced by crossing a pink-flowering plant and a white-flowering plant. This is an example of:

• complete dominance

• incomplete dominance

• codominance

• polygenic inheritance

• multiple alleles

If a dark brown horse and a white horse are bred, the offspring are palomino (tan). This is an example of:

• complete dominance

• incomplete dominance

• codominance

• polygenic inheritance

• multiple alleles

Checkered chickens have an allele for black feathers and an allele for white feathers. This is an example of:

• complete dominance

• incomplete dominance

• codominance

• polygenic inheritance

• multiple alleles

Fur color in rabbits is controlled by a single gene. There are many different phenotypes. What is the best explanation for this?

• complete dominance
