From the above data
1. The frequency of homozygotes and heterozygotes staysconstant for generations, if
• the population is very large,
• the individuals can pair withoutlimitations (if they inhabit the same place at the
same time),
• there is no selection of certain alleles,
• no gene migration occurs, and
• no mutations take place.
F Are these conditions met for the whitesquirrels in Olney, Illinois? Explain your answer.
