9. In a population of giraffes, the gene that determines spot size has two alleles, A for larger spots and a for smaller spots. Giraffes with one of each allele have medium-sized spots. In one generation, the frequency of A is 0.4 and the frequency of a is 0.6. Although spots help the giraffes blend in with their surroundings, they are acted upon by natural selection.
In the next generation, 64% of giraffes have small spots. What percentage of giraffes in the second generation will have medium spots? Large spots? Which phenotype is most adaptive? (Note: this is not a fitness problem, just HW).
