Urgently needed SHORT ANSWER AND PROBLEM SOLVING: (11)1. Rabbits who live in the snowy Himalayan mountains are either white or brown. The brown color is due to a recessive(w) allele while the white color is governed by a dominant allele (W). The Inheritance of this gene follows the rule ofcomplete dominance. You are interested in the evolution of this population. You count the number of rabbits in thepopulation of 150. There are 100 individuals who are homozygous dominant, 40 who are carriers, 10 brown rabbits.A) What is the allele frequency of the dominant W allele in this population? What is the allele frequency of the recessivew allele in this population? Include your calculations in your answer and round to 2 decimals.B) Considering ONLY probabilities involving white rabbits in the population, what is the probability of two cousin rabbitshaving a child who is brown? Show your calculation.C) After a decade, this same population is being analyzed once again. You count 500 rabbits. Genotypically, 340 arehomozygous dominant and 140 are heterozygous for this gene. Phenotypically 20 are brown. Using appropriatecalculations and the Chi-Square table, demonstrate whether or not this population is in Hardy-Weinberg equilibrium

.. Nowadays, newborn babies are required to be tested for phynylketonuria (PKU), an autosomal recessive genetic disorder. If untreated, individual homozygous for PKU suffer mental retardation. In a recent year, 4 PKU babies were detected out of 126,000 tested. Assuming Hardy-Weinberg conditions, what is the frequency of the PKU gene in this population (Give your answer in decimal number with 3 decimal places)?
The next two questions go together. Again with the llamas that display an extraordinary range of fur colors - individuals are either blue, red, or green. But in this isolated population the epistatic relationships between the A and B loci are different. You mate a homozygous red-furred llama (Parent #1) with a homozygous green-furred llama (Parent #2), and all of the offspring are red. You interbreed these red F1s, and the resulting F2 generation consists of 93 red llamas, 27 blue llamas, and 9 green llamas. Assign the genotypes to a modified 9:3:3:1 ratio. red: blue: green What type of epistasis is acting?
House mouse (Mus musculus) Gene of interest: B4galnt2 (encodes glycosyltransferase enzyme) Allele R: Associated with prolonged bleeding due to issues with blood clotting; associated with resistance to bacterial infections due to absence of intestinal expression. Allele C: Associated with increased susceptibility to bacterial infections; not associated with prolonged bleeding. A B C The population is closed; there are no new mice coming in. The cages are setup to allow for random mating. The B4galnt2 gene is not associated with any mating preferences or non-random mating patterns. Studies have shown that mutations in this locus are extremely rare. The population is EXTREMELY large. The population is kept in well maintained environment, free of bacterial infections. The mouse food is supplemented with a low dose of blood coagulator, which helps the blood clot and eliminates any prolonged bleeding. None of the genotypes display any side effects to this medication. The population is…
population is black in colour but about 1/4 of them are white. gene (B) that produces an enzyme that converts a pigment molecule to produce the Black colour. There are 2 alleles of this gene - the dominant B and the recessive b. DNA analysis shows that black individuals have either a BB or Bb genotype and that white individuals have a bb phenotype. However, you have discovered that a small percentage of White individuals have either a BB or Bb genotype. Explain two reasons that could explain this apparent anomaly. They have a BB or Bb genotype but a white phenotype.
A form of learning disabilities and speech impairment results from a recessive mutation in the HERC2 gene. The next 4 questions are about this mutation.

2) The year is 2050. The climate has continued to warm. Areas in northern Canada and Alaska are without snow or ice; the average annual temperature has risen and previously snow-covered areas are now shrub land and some temperate forests. What effect would such a climatic change have on the gene pool of the rabbits? All BUT ONE could apply. In northern Canada, a population of rabbits was predominantly white in color. The allele for white color is recessive (g) while the allele for gray color is dominant (G). Over the last several decades, the average annual temperature of this area has increased and the long-term deposits of ice and snow have become scarce. In this case, the frequency of a previously rare allele becomes more frequent in the population. Choose one.A) The allelic frequency has most likely shifted to 85% GG and 15% gg. B) The dominant allele in the gene pool would become G, the previously rare allele. C) The allele for white, g, would be scarce and perhaps nonexistent…
r-Weinberg Equilibrium Problem Albinism is a rare genetically inherited trait that is only expressed in the phenotype of homozygous recessive individuals (aa) The most characteristic symptom is a marked deficiency in the skin and hair pigment melanin. This condition can occur among any human group as well as among other animal species. The average human frequency of albinism in North America is only about 5 in 100,00. What are the allelic frequencies of a and A in the North American population if this population is in Hardy-Weinberg equilibrium? What are the frequencies of each of the three possible genotypes in the North American population if this population is in Hardy-Weinberg equilibrium?
A certain population of Sistrurus milarius, there exists an allele “d" which has the frequency of 25%. This allele confers the ability to allow the organism to grow to lengths exceeding 3m. This population occurs in the northern 2/3 of Alabama. Out of a population of 80, find the following: # of individuals who are homozygous dominant # individuals who have the recessive disease
two color variations: bright blue and bluish-gray. Bright blue coloration is a recessive condition that is rare in the original population (less than 5% of the birds have the trait). A small flock of 5 wrens is blown by a storm onto a new island that is 100 miles away from their old home. 3 of the 5 birds were blue-gray and the other 2 were bright blue. This new population thrives on the island as it is the only bird species present on an island with lots of food and no predators to hunt them. Over the next 10 years, the 5 birds and their descendants reproduce and populate the island, creating a population that is made up of about 40% bright blue wrens. later, a hawk species is blown over to the island. This hawk hunts the smaller wrens using its excellent vision. The bluish-gray birds blend in better with the landscape compared to the bright blue birds. Name the specific mechanism of microevolution that the wren scenario displays when they were first blown over to the new…
You are studying an autosome trait. There are two alleles, one showing complete dominance over the other. In a population, 84% of the individuals show the dominant phenotype. Assuming that this population is under Hardy-Weinberg equilibrium, which of the following statement is TRUE? 36% of individuals have the homozygous dominant genotype. 40% of the alleles in the population is recessive. 16% of the alleles in the population is recessive. 60% of individuals have the dominant alleles.

What is the frequency of the dominant allele in the gene pool? Record your answer as a value between 0 and 1 rounded to two decimal places. Answer 2)In mice, the waltzing allele (w) that causes the mouse to run in circles due to an inner ear defect is recessive to the non-waltzing allele (W). In an ideal mouse population exhibiting Hardy–Weinberg equilibrium of 150 mice, 70% of the alleles are non-waltzing. What is the frequency of the recessive allele?
