Evolution

Hardy Weinberg

Name______________________________________ Date ___________________

Imagine a species of lizard that has either red eyes or black eyes and that the red eye phenotype is due to homozygosity at a single gene locus R. So R1R1 Black eye; R1R2 Black eye; R2R2 Red. Show your work and use three decimal places in your answer.

What are the genotype frequencies in a population with 940 lizards, 122 of which are red-eyed (assuming they are in Hardy Weinberg equilibrium)?’

What are the allele frequencies in the gene pool of gametes produced by these lizards?

Assuming Hardy Weinberg, what are the allele frequencies in the next generation of babies produced by these adult lizards?

Now assume that snakes who like to eat the lizards can spot the ones with red eyes twice as easily as the black-eyed ones. If you start again with a population of 940 lizards including 122 red eyed ones and snakes eat 83 red-eyed lizards, 18 heterozygous, and 11 homozygous R1 lizards, then what are the genotype frequencies after the snakes have their dinner?

What are the allele frequencies in the gene pool of gametes produced by the survivors?

What are the genotype frequencies in the next generation of baby lizards produced by random mating (assume no predation on the young)?
