1. 12 out of 2400 babies that were born at a maternity hospital died shortly after birth from colonic obstruction due to a recessive allele. Determine the frequency of the lethal allele in the population, expressed as a percent.


2. 10 of 2400 babies born at a maternity hospital died shortly after birth from colonic obstruction due to a recessive allele. What percent of the population would you expect to be carriers of the lethal allele?


3. Suppose that in a fruit fly population the frequency of the recessive allele that codes for short wings (l) is 0.21. What would be the expected homozygous recessive genotype frequency in the next generation? The population is not evolving. Round your answer to two decimal places.
