Codominance Traits

when one allele is not completely dominant over the other - blending of two traits

• Codominance
• Complete dominance
• incomplete dominance
• none of these

condition in which both alleles for a gene are expressed when present - both traits are visible

• Codominance
• Dominance
• Complete dominance
• Incomplete dominance

this image is an example of

• codominance
• dominance
• incomplete dominance

• codominance

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

• Incomplete Dominance
• Co dominance
• Independent assortment
• Recessive inheritance

How many alleles does an individual have for each trait?

• 1
• 2
• 3
• 4

The different forms of a gene are called

• traits
• pollinators
• alleles
• hybrids

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

• all black
• all white
• all gray
• speckled black and white

This type of inheritance pattern shows BOTH traits in possible offspring

• complete dominance
• incomplete dominance
• co-dominance
• dominant pattern

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
