Question

in four oclock flowers, flower color is controlled by a single gene with two alleles. the r allele produces red flower color, and the w allele produces white flower color. these alleles display incomplete dominance, and when both alleles are present, the flowers appear pink. remember, when dealing with incomplete dominance, only capitals are used for the two traits because neither allele exerts dominance over the other. match each of the following genotypes to the correct color of flowers. one genotype description has two possible phenotypic outcomes. rr homozygous rw wr heterozygous ww red flowers white flowers pink flowers

Explanation:

In incomplete - dominance, the $R$ allele gives red color, $W$ allele gives white color, and the heterozygous combination $RW$ (or $WR$) gives pink color. Homozygous $RR$ has two $R$ alleles, resulting in red flowers. Homozygous $WW$ has two $W$ alleles, resulting in white flowers. Heterozygous $RW$ (or $WR$) has both $R$ and $W$ alleles, resulting in pink flowers.

Answer:

RR - red flowers
homozygous (RR) - red flowers
RW - pink flowers
WR - pink flowers
heterozygous (RW or WR) - pink flowers
WW - white flowers
