Once upon a time there was a population of hippies living in an isolated commune called Gone. They had been there for generations, and all members were homozygous for a gene that gave them a preference for crafting necklaces out of green beads, so that every individual had the genotype GG at this locus. In another isolated commune, called Yonder, was a population of hippies that had a genetic propensity for making necklaces out of yellow beads, and everyone was homozygous for a different allele at the same genetic locus; their genotype was YY. Last year (prior to our current socia isolating) everyone repaired their VW buses, and a giant gathering in celebration of the 50th anniversary was held at the Oregon Country Fair. The next few questions will ask you about these two populations that came together at the fair. Was the population that came together at the Country Fair in H-W equilibrium? Remember this population consists of the 12,000 Gone individuals and the 8,000 Yonder individuals. O Yes, they are in H-W equilibrium. O No, they are not.

A botanist studying water lilies in an isolated pond observedthree leaf shapes in the population: round, arrowhead, and scalloped.Marker analysis of DNA from 125 individuals showed theround-leaf plants to be homozygous for allele r1, while the plantswith arrowhead leaves were homozygous for a different allele atthe same locus, r2. Plants with scalloped leaves showed DNA profileswith both the r1 and r2 alleles. Frequency of the r1 allele wasestimated at 0.81. If the botanist counted 20 plants with scallopedleaves in the pond, what is the inbreeding coefficient F forthis population?

1.) “Cystic fibrosis is an autosomal recessive disease that affects the entire body. It also results in the early death of an individual. One in every 2500 children is born with this disorder.” The frequency of the homozygous dominant genotype in the above population is ___________. 2.) “The allele for brown eyes in human beings is dominant over that for blue eyes. Out of 50 individuals in a human population, 8 have blue eyes and 42 have brown eyes.” The value of p for the above population is _____. 3.) The allele for brown eyes in human beings is dominant over that for blue eyes. Out of 50 individuals in a human population, 8 have blue eyes and 42 have brown eyes. The frequency of the recessive allele in the above population is______. 4.) The allele for black coat colour is dominant to the allele for white coat colour in mice. In a population of 500 mice, the frequency of the homozygous recessive genotype (q2) is 0.25. The frequency of the dominant allele in the above…

What is the selective factor, or selective environment, which allows carriers of the sickle-cell allele to have higher fitness than other genotypes? Group of answer choices A-Africa B-sickle-cell disease C-AIDS D-malaria

A population of diploid, outbreeding, sexuall-reproducing rodents, population A, lives on a small island. The population consists of 100,000 individuals a)Are all of the individuals of population A genetically identical? Answer yes or no b) A volcanic eruption carves the island into two populations (A1 and A2, 50,000 individuals each). The rodents cannot cross the lava. Immediately after the eruption, you take 100 individuals from each of populations A1 and A2.  You are shown a DNA sequence chosen at random from the total pool of 200 sequences; can you tell which population, A1 or A2, it comes from?  Answer yes or no. c)How would you determine whether or not individuals from A1 and A2 are reproductively isolated from each other?

Cockroaches from the dormitories at Texas A&M University usually weigh about 1 gram. However, about 100 miles west of the university is a colony of much larger cockroaches in which some individuals obtain a weight of as much as 25 grams. These cockroaches of unusual size (COUS) have apparently evolved to consume the large supply of garbage that exists in the region. If a 25-gram cockroach is crossed with a 1-gram cockroach, their progeny grow uniformly to a size of about 13 grams. If two of these 13-gram (F1) cockroaches are crossed, cockroach sizes from 1 gram to 25 grams are produced. However, the 1-gram and the 25-gram cockroaches are rare, occurring at a frequency in each case of about 1 in 64.   If a 13-gram F1 cockroach is crossed with a 1-gram cockroach, how frequently are 9-gram cockroaches expected? Cockroaches from the dormitories at Texas A&M University usually weigh about 1 gram. However, about 100 miles west of the university is a colony of much larger…

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

a) Suppose the frequency of the recessive allele a for the recessive condition albinism is 0.2 Assume the Hardy-Weinberg distribution.    ai) What is the frequency of albinism in the general population?  aii) What fraction of the population are carriers?  b) In a large population of mice, 0.58 have the recessive genetic condition rsiancer (fictional).  Assume the Hardy-Weinberg distribution. What fraction of mice are carriers? Giver your answer with two digits parts the decimal point. c) In a large population of squirrels,  0.14 have the recessive genetic condition nlourianfilindr (fictional).  Assume the Hardy-Weinberg distribution.  What is the frequency of the dominant allele in this population? Give your answer with two digits parts the decimal point. d) In a large population of chimpanzees,  there is a recessive genetic condition telactalase (fictional).  Assume the Hardy-Weinberg distribution.  If the frequency of dominant allele is 0.77 then what fraction of the population has…

If 9% of an African population is born with a severe form of sickle-cell anemia (ss), what percentage of the population will be more resistant to malaria because they are heterozygous (Ss) for the sickle-cell gene? Assume Hardy-Weinberg conditions. Submit your answer as it is. a) homozygous recessive individuals (q²) b) the recessive allele (q) c) the dominant allele (p) d) homozygous dominant individuals (p²) e) heterozygous individuals (2pq)

It has been hypothesized that people who are heterozygous for the allele that causes the deadly genetic condition cystic fibrosis (which, among other symptoms, reduces fertility) are more resistant to the deadly disease tuberculosis.   Question - if the cystic fibrosis allel protects against tuberculosis the same what the sickle cell allele protects against malaria, then which of the following should be true in comparison between regions with or with out TB. -cystic fibrosis deaths should be more common in regions with tb - CYSTIic fibrosis deaths should be less common in regions with tb -  CYSTIic fibrosis deaths should be equally common in regions with tb -Regional differences in the cystic fibrosis death rate should be purly random and upredictable.
