Concept

Problem: Ina certain type of wild flower, red is the dominant color and white is the recessive color. Phenotypic red flowers can be either homozygous dominant (WW)  of heterozygous (Ww) in genotype. Whereas, the phenotypic white flowers are always homozygous recessive (ww).The phenotypic characteristics of a field of flowers were studied by a group ofresearchers, 64% of the flowers were phenotypically red.What percent of the flowers are genotypically heterozygous (Ww)?A. 36%B. 48%C. 64%D. 24%

FREE Expert Solution

In the problem, the relative frequency of the dominant phenotype has been given, and with it, the recessive phenotype may be computed. The recessive phenotype is, thus, 36%. But, it would still not be enough to be able to differentiate the homozygous dominant from the heterozygous.
