In a study of lizards found on the white sand dunes in Monahans State Park, Texas, you have
discovered that the white body color seen in 16% of lizards found in this habitat is due to a
recessive mutation (w) in the melanocortin-1 receptor. These light-colored individuals match the
surrounding sand dune color and are eaten less frequently by hawks. In this lizard population,
40% of dark-colored, homozygous dominant lizards and 20% of medium-colored, heterozygous
lizards are eaten by hawks. If you start with a population of 100 juvenile lizards, 16 homozygous
recessive (ww), 48 heterozygotes (Ww), and 36 homozygous dominant (WW), what will be the
frequency of the w allele in the next generation? In your calculations round to the nearest whole
lizard individual.
