In a population of jaguars, a gene with two alleles encodes the fur color. Allele B causes melanism (dark fur) and is dominant over allele b, which results in light colored fur. There has been a rare immigration event into a population of jaguars under study, resulting in the following genotype frequencies: 60% BB, 20% Bb and 20% bb individuals. If we assume HardyWeinberg equilibrium for future generations, what would be the genotype frequencies after 5 generations?

2. Alleles D and L are codominant alleles that define fur color in Madagascar lemurs. Lemurs that are homozygous for allele D (genotype DD) have dark brown fur. Lemurs that are homozygous for the L allele (genotype LL) have very light brown fur. The DL heterozygotes are generally light brown, but they have a dark patch or a collar around their neck. Among the 600 Lemurs that you studied on Madagascar, the distribution of genotypes was as follows: Dark brown...

Fur color in dogs can be black, brown or white. The B gene is responsible for fur color. Dogs that inherit a dominant B will have black fur. Dogs that inherit 2 recessive alleles, bb, will have brown color. There is a second gene that contributes to fur color in dogs: gene I. Individuals who inherit a dominant allele, I, at this location, will always have white color. Individuals who inherit the homozygous recessive condition, ii, will be able to...

Question6 1 pts Recall that, in a type of mouse, fur color is determined by alleles at one gene locus; allele A for brown fur and allele a for white. Height is determined by another gene locus; allele B for tall and allele b for short. Each uppercase allele is completely dominant to their respective lower case allele. The 2 gene loci sort or segregate independently. There are no interactions. Mouse 1 (genotype AaBb) mates with mouse 2 (genotype AaBb)...

1. Fixation of Dominant Alleles Start with a population that has a gene with two alleles (A and a) with classical Mendelian dominance that are at equal frequency (p0.5. q 0.5). Assume this first generation is at hardy Weinberg equilibrium. Calculate the genotype frequencies AA- a. Aa b. Now assume some environmental change that makes the recessive phenotype completely unfit (fitness- 0). Calculate the allele frequencies and genotype frequencies in the second generation. (Hint: Your calculations might be easier if...

5. Fur colour in mice is a single gene trait controled by two alleles. In a population of 75 mice, 21 are homozygous dominant, 37 are heterozygous dominant, and 17 are homozygous recessive. What is the frequency of the dominant allele in the population? Show all work and record your answer as a value between O and 1 rounded to two decimal places 6. The Hardy-Weinberg principle states that allele and genotype frequencies remain constant from one generation to the...

In a population of 100 lizards, the “A” allele encodes for spots and is dominant over the “a” allele which encodes for strips. If non-random-mating occurred in this population, meaning lizards only mated with other lizards with the same genotype, how would the allele and genotype frequencies change after two generations of non-random mating? A = 0.5 a = 0.5 I would really appreciate if you could provide an explanation for the steps. Thank you!

The coat color gene of a population of squirrels is defined by a dominant allele G, which encodes a gray coat, and a recessive allele g, which encodes a black coat. In a population, genetic typing reveals the genotypic distribution to be 50 GG, 30 Gg, and 20 gg. If this population is in equilibrium, then what should the genotypic frequency of Gg squirrels in this population be? 0.52 0.46 0.42 0.55
Hair color is determined in Labrador retrievers by alleles at the B and E loci. A...
Hair color is determined in Labrador retrievers by alleles at the B and E loci. A dominant allele B encodes black pigment, whereas a recessive allele b encodes brown pigment. Allele at a second locus affect the deposition of the pigment in the shaft of the hair; dominant allele E allows dark pigment (black or brown) to be deposited, whereas recessive allele e prevents the deposition of dark pigment, causing the hair to be yellow. What type of gene interaction...

1. A particular gene in a given population of individuals has two alleles, A and a. The frequency of the A allele equals the frequency of the a allele. What are the expected genotype frequencies, assuming the population is in Hardy-Weinberg equilibrium? AA = 0.5, aa = 0.5 AA = 0.25, Aa = 0.50, aa = 0.25 O A = 0.5, a = 0.5 The answer cannot be determined because the allele frequencies are not provided.
