This is an example of ___________?

• Incomplete dominance

• Co-Dominance

This type of inheritance pattern shows BOTH traits in possible offspring

• complete dominance

• incomplete dominance

• co-dominance

• dominant pattern

The image above shows the incomplete dominant cross where D codes for straight hair in dogs and d codes for curly hair in dogs. The incomplete dominant trait is wavy hair. Which of the following statements is true about the offspring?

• Only the heterozygous genotype can code for wavy hair.

• Only the homozygous dominant genotype can code for wavy hair.

• Only the homozygous recessive genotype can code for wavy hair.

• The homozygous recessive and homozygous dominant genotypes can code for wavy hair.

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

• Red = RR, white = rr, speckled = Rr

• Red = RR, white = WW, speckled = rw

• Red = RR, white = ww, Speckled = Rw

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