The allele frequency for the spider syndrome allele in a flock of sheep is 0.35. The normal allele N is dominant to the n allele, and homozygous nn lambs do not survive to reproduce. In the flock, all NN and Nn animals are retained, and all nn animals are removed from the herd. Determine the allele and genotypic frequencies in the flock following a single generation of selection

Hardy Weinberg assignment P + Q = 1 In which P represents frequency of dominant allele and Q represents frequency of the recessive allele P2 + 2PQ + Q2 =1 P2 represents frequency of homozygous dominant 2PQ represents frequency of heterozygous Q2 represents frequency of homozygous recessive Consider a population of beetles on an island. There are 1000 beetles and they have different colored wings. Black wings are dominant over silver wings. Calculate the allele and the genotypic frequencies in...

White wool in sheep is controlled by a dominant allele R, and black wool by the recessive allele r. In an isolated population of 6530 sheep, 514 are black, 4981 are heterozygous, 1035 are homozygous white. When will this population be expected to reach Hardy-Weinberg equilibrium? in the next generation in two generations it already is in equilibrium impossible to tell it will not reach equilibrium A population has the following genotypic distributions: A^M A^M...

Determining if allele frequencies are changing from one generation to the next (microevolution) from the number of individuals of each genotype present: The following steps are used to determine if allele frequencies are changing: Calculate Allele frequency from the number of individuals of each genotype Calculate expected genotypic frequencies and individuals in a population from allele frequencies: Test the goodness of fit between the data and the Hardy Weinberg equilibrium model generated expectations. The following problems are the calculations used...

In gerbils there is a recessive mutant gene that causes a lethal condition. For the purpose of this problem let the symbol A denote the normal allele and a the mutant. In heterozygote individuals who carry both versions of the allele (Aa), this causes a white spotting color pattern. Homozygotes for the mutant (aa) die as embryos and are never seen in live gerbils. Since the mutant allele is lethal in the homozygous form, natural selection will occur against the...

8. You are studying an annual wildflower population. Flower color is either red or yellow and is controlled by a single locus with 2 alleles: R and y. Red is dominant to yellow, and both homozygous RR individuals and heterozygous individuals have red flowers, while yy individuals have yellow flowers. You have been studying this population for a long time and have seen fairly consistent allele frequencies for these two colors, with R=0.65 and y=0.35. Two years ago, a new...

A wildflower native to California, the dwarf lupin (Lupinus nanus) normally bears blue flowers but occasionally bears pink flowers. Flower color is controlled by a single diploid locus, with the blue allele (B) completely dominant over the pink allele (b). In a wild population of lupins, there are 43 pink lupins and 3398 blue lupins, for a total of 3341. Calculate the genotype and allele frequencies of this population, assuming that the population is in Hardy-Weinberg equilibrium: Genotype frequency of...

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...

Wild turkeys can see more clearly and in more detail than humans. Hence, turkey hunters need to dress themselves, and their weapons, in camouflage. Pretend that turkeys have a single gene, the "A" gene, which controls eyesight. (This is probably not really true, the pattern of inheritance is probably much more complicated.) Imagine that turkeys with a dominant allele (A) can see well while turkeys that are homozygous recessive cannot see as w wrell. A small population of 1000 wild...
