How can you determine the genotype of a plant showing the dominant phenotype of red color?
A. The phenotype reflects the genotype, so the plant must be homozygous for the trait.
B. Cross the red plant with a white plant to see if any white plants appear.
C. Cross the red plant with other red plants to see if any white plants appear.
D. Cross the red plant with a white plant to see how many red plants appear.
E. Cross the red plant with another red plant, and then cross the F1 population with each other to see if any white plants appear.

Incomplete dominance is when
A. the phenotypes of a heterozygote and a homozygous dominant are indistinguishable. B. the phenotypic expression at one locus alters the gene at a second locus. C. the phenotype of a heterozygote clearly exhibits the phenotypes of both parents (it is not an intermediate). D. an allele is dominant at some times and recessive at others. E. the phenotype of a heterozygote is not the same as either parent, but it is somewhere between the two parents.
