Question

Imagine you are trying to test whether a population of flowers is undergoing evolution. You suspect there is selection pressure on the color of the flower: bees seem to cluster around the red flowers more often than the blue flowers. In a separate experiment, you discover that blue flower color is dominant to red flower color. In a field, you count 600 blue flowers and 200 red flowers. What would you expect the genetic structure of the flowers to be?

A. 25% R. 75% B
B. 14.4% R, 24.5% B
C. 50% R. 50% B
D. 25% RR, 25% BB. 50% BR
E. 14% RR, 25% BB, 61% BR

Answer 1

The expected genetic structure of the flowers would be 25% RR (homozygous recessive red flowers) and 75% BB (homozygous dominant blue flowers).

Step-by-step explanation:

The expected genetic structure of the flowers would be:

• 25% RR (homozygous recessive red flowers)
• 75% BB (homozygous dominant blue flowers)

Based on the given information, we know that blue flower color is dominant over red flower color. Since there are 600 blue flowers and 200 red flowers, we can calculate the expected genetic structure using the Hardy-Weinberg equation. In this case, there would be 25% red flowers (RR genotype) and 75% blue flowers (BB genotype).
