Dominant alleles are represented by a(n)

• phenotype
• lower case letter
• upper case letter
• punnett square

this image is an example of

• codominance

• dominance

• incomplete dominance

• polygenic traits

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

In some carnations, flower color exhibits codominance. Identify the correct genotypes for red, white, and speckled carnations.

• Red = RR, white = rr, speckled = SS

• Red = RR, white = WW, speckled = SS

• Red = RR, white = RW, Speckled = WW

• Red = RR, white = WW, speckled = RW
