Alright. For practice, try this problem:
"The allele for the ability to roll one's tongue is dominant over the allele for the lack of this ability. In a population of 5000 individuals, 45% show the recessive phenotype (bb). How many individuals would you expect to be homozygous dominant (BB) and heterozygous for this trait?"
Make me look bad for choosing to ask you this question.
