You sample a population of cats whose pelt color is determined by a single gene. The dominant allele codes for a green cat and the recessive allele codes for a yellow pelt. The population consists of 1000 cats, 750 cats are green and 250 are yellow. What proportion of the alleles are yellow?

Which of the following refers to structures that share an evolutionary history, but that may currently be used for different functions?
