P-0.6 In a given population of grizzly bears, 29 of a total of 145 animals exhibit a light fur colour which is controlled by a recessive allele. Four generations later, 36 out of the total population of 180 bears exhibited the same light fur trait. Show the steps involved in determining whether evolution has occurred in this grizzly bear population.

After several generations, 260 out of 5000 of the animals display a recessive trait (aa), the same percentage as at the beginning of the breeding program. The rest of the animals show the dominant phenotype,...

Case B: In this population, the frequency of the dominant allele, B, is 0.5 and the frequency of the recessive allele, b, is 0.5. However, in this situation any individual who is born with the dominant trait has a 50 % chance of not surviving to reproductive age. Assuming that mating is still random, what will happen to the allele frequencies (p and q) after 5 generations? (le. Will one allele increase or decrease?) Prediction (1 mark): Reason (2 marks):...

a population of rock pocket mice were observed on a black substrate. the population contained individuals with both black and white fur. The black allele (B), is dominant over the white allele (b). A scientist in the field counts 640 black mice and 360 white mice out of 1000 total mice. She is interested in tracking evolution in the population. Please show your work for below questions. A)What is the frequency of the white allele? B)What is the frequency of...

The occurrence of the NN blood group genotype in the US population is 1 in 400, consider NN as the homozygous recessive genotype in this population. You sample 1,000 individuals from a large population for the MN blood group, which can easily be measured since co-dominance is involved (i.e., you can detect the heterozygotes). They are typed accordingly: BLOOD TYPE GENOTYPE NUMBER OF INDIVIDUALS RESULTING FREQUENCY M MM 490 0.49 MN MN 420 0.42 N NN 90 0.09 Using the...

Testing the goodness of fit between the data and the Hardy Weinberg equilibrium model generated expectations. 4.1 In a species of bird, feather color is controlled by genes at a single locus, with the red feather allele dominant to the yellow feather allele. A population has 22 red and 14 yellow birds, with 9 of the red birds having a homozygous dominant genotype. Is this population in equilibrium? Calculate p and q from the number of individuals of each genotype:...

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...
