1) Suppose that in a fruit fly population the frequency of the recessive allele that codes for short wings (l) is 0.30. What would be the expected genotype frequencies in the next generation?

2) In a pea plant population, the dominate allele for tallness (T) has a frequency of 0.64. What percent of the population would be expected to be heterozygous (Tt) for the height gene?

3) If 85 percent of the population of Alberta has Rh+ blood, a dominant trait, what percentage of Albertans would you expect to be heterozygous for this trait?

4) In the Caucasian population of North America, one out of every 10000 babies is born with recessive condition known as phenylketonuria (PKU). This condition is controlled by single pair of alleles. People who are homozygous recessive for PKU gene completely lack the enzyme that is necessary to metabolize the amino acid phenylalanine into harmless by-products. The presence of this amino acid in a baby's brain. What percentage of the Caucasian population of North America would you expect to be heterozygous for the PKU allele?

5) A population has two alleles for a particular gene (B and b), and the allele frequency of B is 0.70. The frequency of the heterozygous genotype is

A. 0.30

B. 0.09

C. 0.49

D. 0.42
