Incomplete Dominance and Codominance

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

• Incomplete Dominance
• Codominance
• Independent assortment
• Recessive inheritance

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

NGSS.HS-LS3-1

This type of inheritance pattern shows BOTH traits in possible offspring:

• complete dominance
• incomplete dominance
• co-dominance
• Indomitable 

When two or more alleles for a trait exist in a population.  Ex: Different hair colors or blood types

• SHAZAM!
• Multiple Genes
• Multiple Alleles
• Polysaccharide

NGSS.HS-LS3-2

There are three common alleles for the gene that controls blood type. These are A,B, and O. Their Dominant/recessive relationship is: 

• A and O are codominant and B is recessive
• O is dominant and A and B are corecessive
• A and B are codominant and both are dominant to O
• B and O are codominant and both are dominant over A
