homework - non-mendelian genetics
consider a species of flower where a genotype of rr results in red flowers and a genotype of ww results in white flowers. if a rw genotype results in pink flowers, this is an example of
○ incomplete dominance
○ complete dominance
○ codominance
○ epistasis

Explanation:

• Incomplete dominance occurs when the heterozygous phenotype is a blend of the two homozygous phenotypes. Here, the \(RW\) genotype (heterozygous) results in pink flowers, which is a blend of red (\(RR\), homozygous) and white (\(WW\), homozygous) flowers.
• Complete dominance would mean one allele completely masks the other (e.g., if \(RW\) was red like \(RR\)).
• Codominance involves both alleles being expressed simultaneously (e.g., patches of red and white in the flower, not a blend).
• Epistasis is when one gene affects the expression of another gene, which is not the case here.

Answer:

Incomplete dominance
