Dominant alleles are alleles whose trait ......... shows up when the alleles is present.

• always

• never

• sometimes

• usually

What type of inheritance pattern do two alleles for a gene follow if their traits blend together on the offspring?

• Incomplete dominance

• Codominance

​ ​ (a)   have both alleles equally expressed, while ​ (b)   has an intermediate between the two parents, neither trait is dominant.

• codominant traits

• incomplete dominance

• dominant

• recessive

What is incomplete dominance?

• a blending of two traits (pink snap dragons)

• when one trait shows up and the other doesn't

• when both traits show up (speckled chickens)
