Evolution
Question
1. 10% of a population is blue-eyed (a recessive trait).
Use the H-W law to determine what percent of the
population is heterozygous for not having blue eyes).
2. What does natural selection directly work on?
3. If 90% of a population has a widow’s peak (dominant
trait), what percent of the population will show the
recessive trait? Be heterozygous for the trait?
