Textbook Question
Chapter 13, Problem 14PS
Imagine that the presence or absence of stripes or the snails from the previous question is determined by a single gene locus, with the dominant allele (S) producing striped snails and the recessive allele (s) producing unstriped snails Combining the data from both the living snails and broken shells, calculate the following: the frequency of the dominant allele, the frequency of the recessive allele, and the number of heterozygotes in the observed groups.
Striped Shells | Unstriped Shells | |
Number of live snails | 264 | 296 |
Number of broken snail shells | 486 | 377 |
Total | 750 | 673 |

About 8% of the men in a population are red-green color blind (because of a sex-linked recessive allele). Answer the
following questions, assuming random mating in the population, with respect to color blindness.
a. What percentage of women would be expected to be color blind?
b. What percentage of women would be expected to be heterozygous?
c. What percentage of men would be expected to have normal vision two generations later?
Imagine you are studying a population of finches on one of the Galápagos Islands. You have been recording many of the birds’ physical traits, including the length of both wings. You observe that for 80% of individuals measured, the length of the left wing is not significantly different from the length of the right wing (in other words, they are symmetrical). But for about 20% of birds measured, the wing lengths are asymmetrical. This distribution is true from generation to generation. Suddenly, a rare 5-day windstorm takes over the island. After the storm, you spend the next several days netting each bird on the island that survived the storm. You discover that 85% of the birds with symmetrical wings survived the storm, whereas only 5% of the birds with asymmetrical wings did.
a. Propose a hypothesis to explain this observation.
b. If such storms become increasingly common due to changes in climate, how might you expect the population to change over time with respect to wing symmetry?
Imagine a locus with two alleles. Mutation at this locus changes one allele to the other (i.e. it does not create a new allele). If the rate of mutation from allele 1 to allele 2 is 0.00005 and the rate of mutation from allele 2 to allele 1 is 0.01, what is the equilibrium frequency of allele 2 (Give your answer to 5 decimal places)?

In a heterogeneousenvironment, the allele frequencies are D = 0.7 and d = 0.3. Thispolymorphism is maintained because the environment has somedimly lit forested areas and some sunny fields. During a hurricane,a group of 1000 insects is blown to a completely sunny area. In thisenvironment, the relative fitness values are DD = 0.3, Dd = 0.7, anddd = 1.0. What are the predicted allele frequencies in thenext generation?arrow_forwardHow Can We Measure Allele Frequencies in Populations? In a population where the females have the allelic frequencies A = 0.35 and a = 0.65 and the frequencies for males are A = 0.1 and a = 0.9, how many generations will it take to reach HardyWeinberg equilibrium for both the allelic and the genotypic frequencies? Assume random mating and show the allelic and genotypic frequencies for each generation.arrow_forward
- Clines in body size have been observed in many species, such as the latitudinal cline in moose shown in Figure 8.2 (shown in the previous question). How might you determine whether a cline in body size was caused by clines in allele frequencies? Which of the following is NOT one of the strategies to test this? Group of answer choices A.) Measure and assess the morphological character in multiple individuals along the cline and statistically compare them for significant differences. B.) Swap individuals or seeds from one end of the cline with those at the other end of the cline, and vice-versa, and then measure and assess how they grow. C.) Grow or raise individuals from different parts of the cline under the same conditions, in a common garden experiment, and then measure and assess how they grow. D.) Identify the genes coding for that morphological character, sequence them in multiple individuals across the cline, and then compare them for variation in sequence, structure,…arrow_forwardThere are two different phenotypes of a moth species, black and light grey, which are predated upon by birds. The more recently evolved black colour, is the dominant allele, B, while the recessive allele, b gives a light grey colour.
