Suppose a population of 1000 people is in H-W equilibrium, if 84% of this population can taste PTC, how many are heterozygotes, considering that ability to taste PTC is inherited as a dominant allele?A. 480B. 400C. 580

167 10. (5) You have sampled a population of lady beetles, in which black spots (B) is dominant to no spots (b). You know that the percentage of individuals with the homozygous recessive genotype is 32%. Use that information to calculate the genotype frequency of the BB genotype and the Bb genotype.

From the 1700s to the early 1950s there was an unusually high percentage of deaf people on the island of Martha’s Vineyard off the coast of Massachusetts, USA.Deafness was a recessive hereditary trait, and there was a very small population of people living on the island. This meant that almost everyone had both deaf and hearing siblings. In the mid-1850s, the frequency of deaf people on the island was well over 30% higher than the U.S. national average.The high frequency of deaf individuals on the island of Martha’s Vineyard is best explained by Select one: a. genetic drift b. founder effect c. non-random mating d. bottleneck effect

When a plant breeder crossed two red roses, 78% of the offspring had red flowers and 22% had white flowers. According to these results, the allele for red flowers is most likely: A. Recessive  B.  Dominant C. Incompletely Dominant D.  Influenced by multiple alleles
