Week 2 Review Questions

How do morphological, developmental, and molecular homologous represent examples of evolution?

How do whale hind limbs, squid eyes, and bacterial flagella represent examples of evolution?

What’s the difference between a dominant allele, a recessive allele, a homozygote, and a heterozygote?

Why is Hard-Weinberg Equilibrium a null hypothesis, and why is this a useful tool for studying evolution?

In a diploid grasshopper population of 50 individuals, if there are 40 recessive alleles for yellow antennae, what is the frequency of dominant alleles for the black antennae? What would you expect to be the genotypic and phenotypic frequencies in the next generation if it were in Hardy-Weinberg equilibrium?

A population of Geckos has two alleles, G and g, at a locus for tail color. The allele frequency of G is .22, and the genotype frequency of gg is .31. Is tail color evolving in this population?
