1. in snapdragons, flower color is controlled by incomplete dominance. the two alleles are red (r) and white (w). the heterozygous genotype is expressed as pink.

a) what is the phenotype of a plant with the genotype rr? __________
b) what is the phenotype of a plant with the genotype ww? __________
c) what is the phenotype of a plant with the genotype rw? __________

Explanation:

a) The problem states the red allele is (R), and homozygous RR expresses the red phenotype.
b) The white allele is (W), so homozygous WW expresses the white phenotype.
c) In incomplete dominance, heterozygous RW is defined as pink.
