After World War II, the allele frequency for brown eyes was B=0.4 and blue eyes b=0.6

The phenotype frequency in the US currently is brown = B 83% and blue b=17%

Has the US population evolved with respect to eye color?

Please help me understand what this question is asking? Do I need to use the Weinberg equation if so, please solve so I can see how to explain the answer?

Answer #1

​​​The question is asking for whether any evolution is occurred or not in US in the present days from the world war II

Yes, you should use Hardy-Weinberg law to calculate the allelic as well as genotypic frequency to test the occurrence of any evolution for a particular trait.

    4. In a given population, 16% of the population has blue eyes and 84% has brown eyes. Although eye color is a polygenic trait, let us assume for this problem that the brown-eyed allele is dominant to the blue-eyed allele and that the population is in Hardy-Weinberg equilibrium. What are the gene frequencies for brown eyed and blue-eyed alleles? = '16 Pa Brown-eyed allele frequency: _ qe 0.4 Pa 0.4 Blue-eyed allele frequency: - In this same population, there are...

    Human Genetics Although we humans are fantastically made, are quite complex, and our traits are often coded by many genes, some traits are coded by single gene pairs. The following table is a survey to help you determine your genotype, based on phenotype traits. Keep in mind the terms homozygous dominant (AA) will have the dominant trait, homozygous recessive (aa) will have the recessive trait, and heterozygous (Aa) will have the dominant trait. If you have the dominant trait, you...
