Unit 8 Genetics Review

A calico cat shows both the traits for orange fur and black fur. What kind of inheritance pattern is this?

• Incomplete Dominance

• Co Dominance

• Sex-Linked

• Polygenic

A red flowered plant (RR) breeds with a White flowered plant (WW). The gene for petal color in these plants expresses incomplete dominance. What percentage of the offspring will have pink (RW) flowers?

• 0%

• 25%

• 50%

• 100%

A roan cow shows co-dominance in fur color (orange and white). What is the phenotype ratio expected if a roan cow and a roan steer mate together?

• 4: Orange and White
• 1: Orange : 1 White
• 2 Orange: 2 Orange and White: 0 White
• 1: Orange: 2 Orange and White: 1 White

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

• incomplete dominance

• co-dominance

• complete dominance

• recessive pattern
