Albinism is a recessive condition (aa) in which body cells cannot manufacture the pigment melanin, which colors eyes, hair, and skin. Normal pigment production is dominant (AA or Aa). A normally pigmented woman marries a normally pigmented man. To their surprise, they have an albino child. Draw a Punnett square and answer the following questions.

What is the genotype of the parents?

• AA

• Aa

• aa

• A?

Black feathered chickens and white feathered chickens produce "checkerboard chickens". Both the black and white alleles express themselves fully. This is an example of

• incomplete dominance

• co-dominance

• polygenic trait

• multiple alleles

Norb has curly hair (CC). His wife has straight hair (cc). All of his children have wavy hair (Cc). What type of inheritance pattern is this, where the heterozygote is a "blend" of the two alleles?

• incomplete dominance

• co-dominance

• polygenic trait

• multiple alleles

Hair color, eye color, skin color, height, intelligence are all traits that have a huge variety of phenotypes in the population. That is because these traits are examples of

• incomplete dominance

• co-dominance

• polygenic trait

• multiple alleles
