Question asked by Filo student
Flower color in snapdragons is an incompletely dominant trait. In a population of 1000 offspring between two heterozygous parents (pink flowers) the following phenotypes were recorded: 300 red-flowered, 540 pink-flowered, and 160 white-flowered. Use this data to calculate the genotype and allele frequencies. Alleles: \( \mathrm{C}^{\mathrm{R}}= \) red pigment; \( \mathrm{CW}^{\mathrm{W}}= \) white pigment Genotypes: \( C^{R} C^{R}= \) red flowers; \( C^{R} C^{W}= \) pink flowers; \( C^{W} C^{W}= \) white flowers
