Leg length is polymorphic within a population of lizards, with much of the variation controlled by (segregating for alleles A/B). Homozygous BB lizards have short legs and move slowly, and so are easy prey to hawks. As a result, only 20% of them survive to reproduce. Homozygous AA individuals are fast but struggle to hold onto branches during hurricanes, and so only 50% of them survive to reproduce. AB heterozygotes are both relatively fast and can grip branches well. 80% of them survive to reproduce. The frequency (q) of the B allele at birth is 10%. Calculatehe absolute mean fitness of the population using the mean fitness formula.
