Concept Check 3.1. Grey squirrels, Sciurus carolinensis, abound in upstate New York.Contrary to their common name, not all members of this species are grey in color. Somepopulations have a considerable number of melanistic individuals who appear quite dark,almost black. If a population north of Geneva has 30% melanistic individuals, find thefollowing probabilities and expected values:(a) A random sample of 18 has 4 melanistic squirrels.(b) A random sample of 18 has 4 or less melanistic squirrels.(c) A random sample of 18 has more than 4 melanistic squirrels.(d) The expected mumber of melanistic squirrels in a random sample of 18 individuals.(e) The expected variance for samples of size 18.

Hardy-Weinberg Equilibrium is a concept that serves as a benchmark for researchers to analyze gene…

Problem 4) About 7% of men in a population are red-green colour blind due to a sex-linked recessive gene. Assuming random mating in the population with respect to colour blindness; a) What percentage of women would be expected to be colour blind? b) What percentage of women would be expected to be heterozygous? c) What percentage of men would be colour blind in the next generation?
question- If we digested 4.5 μg of total chDNA with Sal I in a total volume of 60μL and we want to set up a 3:1 ratio using 0.1 μg of digested pGEM, how many μg of the chDNA do we ideally want and in what volume? Answers: a. 1.2 μg in 16.0 μL b. 0.3 μg in 4.0 μL c. 0.9 μg in 12.0 μL d. 0.6 μg in 8.0 μL
Prediction of Genetic Gain. If the milk yield of a herd of cow is 6,479 kg while those kept for breeding is 6,890 kg, and the h2 estimate of milk yield is 0.85. And the generation interval of dairy cattle is 4 years. What will be the expected genetic gain in the milk yield of the next generation? (Units should be specified and round off to 2 decimal place)

Recall p + q = 1 p2 + 2pq + q2 = 1 p is the frequency of the dominant allele q is the frequency of the recessive allele p2 is the frequency of homozygous dominant genotype q2 is the frequency of homozygous recessive genotype 2pq is the frequency of heterozygous genotype Show work for all answers In a population of birds, 60 have curved beaks (a recessive trait). If the population has 400 birds, what percent of them will be heterozygous for straight beaks? How many of them will be heterozygous?
Recall p + q = 1 p2 + 2pq + q2 = 1 p is the frequency of the dominant allele q is the frequency of the recessive allele p2 is the frequency of homozygous dominant genotype q2 is the frequency of homozygous recessive genotype 2pq is the frequency of heterozygous genotype Show work for all answers In a population of lizards, the allele for short tails has a frequency of 0.2. When the population is sampled and genotyped it is found that 50% are homozygous dominant for long tails, 25% are heterozygous and 25% have short tails. Is the population in Hardy Weinberg equilibrium? Why or why not? If not, provide a possible explanation as to why.
54. Very similar species of salamanders may breed in different habitats. Some species breed in ponds, while other species prefer to breed in streams. Therefore, these similar species do not even encounter one another. This is an example of what type of reproductive isolating mechanism? Explain
Describe what a pyramid of numbers would like if an ecologist models the relationship between bird parasites, blue jays, and oak trees in a hectare. Does this match the energy flow pyramid?
Question:- Assume that the probability that any child born in the population will be a boy is 0.51 and the probability that it will be a girl is 0.49. If a family has six children, what is the probability they will have 3 boys and 3 girls?
Question:- Walruses that live on islands near Alaska have a thick fat layer under their skin; however, their ancestors did not have a fat layer as thick as it is now. In your own words and based on course material only, describe in detail the process that would have resulted in this population evolving a thicker fat layer over time.
Question:- Consider in a population, the frequency of allele ‘A’ is 50%, and frequency of allele ‘a’ is 50%, the rate of mutation converting A to a is u = 10 to the negative 5. After 10000 generations, the allele frequency of A will be
