Textbook Question
Chapter 26, Problem 21PDQ
In an isolated population of 50 desert bighorn sheep, a mutant recessive allele c when homozygous causes curled coats in both males and females. The normal dominant allele C produces straight coats. A biologist studying these sheep counts four with curied coats. She also takes blood samples from the population for DNA analysis, which reveals that 17 of the sheep are heterozygous carriers of the c allele. What is the inbreeding coefficient F for this population?

- Sickle cell anemia is caused by a recessive allele at a single gene. As we discussed in class, being a homozygote for the sickle cell allele is almost always lethal, but heterozygotes tend to be resistant against malaria although they have a mild form of anemia. Because of this heterozygote advantage, the allele for sickle cell anemia has a frequency of more than 10% in some human populations. How would present allele frequencies of the sickle cell allele change, if there was no heterozygote advantage or disadvantage (that is, that heterozygotes would be identical to ‘normal’ homozygotes – no malaria resistance, no anemia)? How would the change in sickle cell allele frequencies compare to scenario a (extirpation of malaria)arrow_forwardSnow geese (Chen caerulescens) come in two color types, white “snows” and “blues” with dark bodies. A single gene controls coloration, where the dark (“blue”) allele (D) is dominant. A population of 30,012 geese includes 9236 dark individuals. Genetic testing reveals that 7636 of the 9236 dark individuals are heterozygous (Dd). What is the actual frequency of genotype dd?

- Among a population of lizards inhabiting an arid habitat, the skin color is controlled by two alleles—B (brown skin color) that is dominant over b (green skin color). The green lizards comprise only 4 percent of the population whereas the brown lizards comprise the rest. Over a long period of time, increased rainfall in the area leads to transformation of the habitat, with growth of shrubs and small trees. The brown and green lizard numbers almost reverse with the green lizards approaching 81 percent of the total population. Calculate the allele frequency for the green skin color before and after the climate change occurred. Why did the brown lizard, which initially had greater relative fitness than the green lizard, reduce in number drastically? A. 2, 9; because relative fitness is dependent on environmental conditions B. 0.2, 0.9; because relative fitness is dependent on environmental conditions C. 0.2, 0.9; because the green lizard population acquired new…arrow_forwardA very large population of rabbits has been allowed to breed randomly in a laboratory research program. The rabbits vary in their coat colour, which is either gray or black. After many generations, 25% of the rabbits display a recessive phenotype for gray coat colour (aa), the same percentage as at the beginning of the breeding program. The other 75% of the rabbits show the dominant black coat phenotype, with heterozygotes (Aa) indistinguishable from the homozygous dominants (AA) What is a reasonable conclusion explaining the fact that the frequency of the recessive trait (aa) has not changed over time? a. There has been sexual selection favouring allele a b. The two phenotypes have about equal fitness under laboratory conditions C. The population is undergoing genetic drift d. The genotype AA is lethalarrow_forwardGiven the following pedigree (note that C7C, M4C, N2X, H6C, G9X, J1C, B8X, and P2X are the names of animals): arrow_forward
- In the genetics unit you learned that sickle cell anemia is an autosomal recessive condition. In 2016, assume in the City of Markham there are 1000 people out of 300000 people who have sickle cell anemia. Assume global warming continues for the next 50 years and in the year 2066 there are 20000 people out of 500000 in Markham who have sickle cell anemia. a)What are the allele frequencies in 2016? What are the allele frequencies in 2066? Is microevolution evident? b)Due to global warming, assume the numbers of malaria carrying mosquitoes in Markham dramatically increased between 2016 and 2066. What do you believe is the main cause of the microevolution in Markham?
