Question 2:What patterns do you observe in Wing Length from 1973 to 1978? EVOLUTION ASSESSMENT - FINCHESGalápagos Ground FinchesBetween 1973 and 1978, the population of ground finches (a type of small bird) on the Galápagos Islandsdecreased. Scientists made observations of the population throughout that time period. They recordedand graphed differences in the distribution of traits over time. The two sets of graphs below come fromthe data they collected.Beak Length for Ground Finches Observed in the Wet Seasons of 1973 and 1978Wet 1973: all finches# of finches30# of finches25201510503025201510512-010$4.980-8430.0-11.5-11.9Beak Length (mm)Source: inquiryHub35.0-39.940.0-44.912.5-12.913.0-13.413.5-13.914.0-Wing Length for Ground Finches Observed in the Wet Seasons of 1973 and 1978Wet 1973: all finches65.0Wing Length (mm)Source: inquiryHub70.0-74.9# of finches75.0-3025# of finches20105030252015O1050Wet 1978: all finches7.0-747.5-7.980-8.485-809.0-949.5-9.910.0-130.0-34.910.5-10.911.0-11.411.5-11.912.0-12.412.5-Beak Length (mm)Source: inquiryHubWet 1978: all finchesWing Length (mm)Source: inquiryHub13.0-13.413.5-13.914.0-75.0-

Which of the following conclusions is BEST supported by this evidence? Sexual selection was a mechanism of evolution driving the increased frequency of dark morphs. Light colored moths survived better regardless of habitat, suggesting that their fitness was higher than that of the dark morphs. Natural selection favored different alleles for moth color in different environments. Genetic drift randomly changed allele frequencies over time in this population.

Now, there is a white population of foxes that lives there. Which of the following was the primary change that occurred gradually over time in the Arctic fox population, eventually resulting in foxes with white fur? O The fur color of each individual fox within the population gradually changed. O The frequencies of foxes with different fur colors within the population changed. O Mutations occurred to meet the need of the fox population in the new environment. O Foxes that survived longest gained white fur in their old age, which they passed on to their offspring, tion 15
If these conditions held constant – what would the expected heterozygosity be in thepopulation today (2018 to deal with a clean integer value for generations)?1b. In 1884 the population had grown to 106 when disaster struck the island. Of the 19 adult menon the island, 15 were in the same fishing boat that capsized, leaving only 4 adult men alive onthe island. These desperate times may have changed the sex ratio of the breeding population onthe island. Let’s say that now, each man fathered children with an average of 1.5 differentwomen (male:female ratio of 1:1.5). If we start back with a heterozygosity of 0.5 from this point,given the effective population size on Tristan da Cunha, what is the expected heterozygosity inthe current population 7 generations later?1c. The scenarios described in 1a and 1b are examples of which two evolutionary phenomena,respectively?

Pikas are small mammals that live at high elevations on the talus slopesof mountains. Most populations located on mountaintops in Coloradoand Montana in North America are isolated from one another: the pikasdon’t occupy the low-elevation habitats that separate the mountaintopsand don’t venture far from the talus slopes. Thus, there is little gene flowbetween populations. Furthermore, each population is small in size andwas founded by a small number of pikas.A group of population geneticists proposes to study the amount ofgenetic variation in a series of pika populations and to compare theallelic frequencies in different populations. On the basis of the biologyand distribution of pikas, predict what the population geneticists willfind concerning the within- and between-population genetic variation.
