1.9.You are a genetiCıst studying a population of 100 barn swallows. You are particularlyinterested in one gene, and upon examining the alleles present, you find one allele is quitecommon, accounting for 80 of the alleles in this population. What is the frequency of this allelein the population?4.5.The ability to breathe fire in dragons is controlled by a single gene with two alleles. Thefire-breathing allele (F) is dominant to the non-fire breathing allele (f). In a population of 600dragons, 150 dragons are non-fire breathing (ff) and the rest can breathe fire (either FF or Ff)The population is in Hardy-Weinberg equilibrium. The frequency of the dominant allele (F) isrepresented by "p and the frequency of the recessive allele (f) is represented by "q". Recall theallele frequency is p+ q = 1 and the Hardy-Weinburg equation is p2 + 2pq + q2 = 1 (2 pts).What is the frequency of the recessive allele (f)? Hint: you can figure out the frequencyof ff, which is equal to q2, but then you need to solve forA.q.What is the frequency of heterozygous individuals (Ff) in the population? Hint: thiswould be equal to 2pq. You already solved for q, so you need to determine p before you cansolve for 2pq.B.6.Two populations of frogs are separated from each other by a large distance, however, afew male frogs make the journey each year to breed with females in the other population. Wouldyou expect these populations to eventually become separate species? Why or why not?

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

fire-breathing allele (F) is dominant to the non-fire breathing allele (f). In a population of 600
dragons, 150 dragons are non-fire breathing (ff) and the rest can breathe fire (either FF or Ff)
The population is in Hardy-Weinberg equilibrium. The frequency of the dominant allele (F) is
represented by "p and the frequency of the recessive allele (f) is represented by "q". Recall the
allele frequency is p+ q = 1 and the Hardy-Weinburg equation is p2 + 2pq + q2 = 1 (2 pts).

3. a. Why are most populations not in Hardy Weinberg Equilibrium? b. There is an ancient village population of humans. We know very little about this population. How can we use genetics to determine if the societal system of the village was matrilocal or patrilocal? c. There was variation in a rat phenotype (coat color.) The coat colors ranged from dark color coats to light color coats. As the rats migrated into the basements of campus, the light color rats were more likely to be caught by the campus cat. Over time, the basement rat population shifted to entirely dark color coats. This is an example of what kind of selection? d. Explain how a genetic bottleneck could lead to higher susceptibility of a disease, such cancer, in that population.
1. A sample of 600 individuals from a population is examined for the presence of the HindIII polymorphism in an autsomal Sca gene. There are two alleles of Sca gene, A and a. The results are 14 individuals are AA, 212 are Aa, 374 are aa. Please answer the following questions accordingly? How many alleles are present in the gene pool in the sample population fort he Sca gene? What are the genotype frequencies? What are the frequencies of A and a alleles?

Bill, who is raising cockroaches in his dorm room, finds that thefrequency of the gene for curved wings in his cockroach population is0.6. In his friend Joe’s apartment, the frequency of the gene for curvedwings is 0.2. One day Joe visits Bill in his dorm room, and severalcockroaches jump out of Joe’s hair and join the population in Bill’sroom. Bill estimates that, now, 10% of the cockroaches in his dormroom are individual roaches that jumped out of Joe’s hair. What is thenew frequency of curved wings among cockroaches in Bill’s room?
