Question: "Determine the genotypic frequencies of offspring for a genetic trait with two alleles, R and r, with the previous generation's allelic frequencies of R=0.1 and r=0.9."
My professor said that you can use the formula p^2+2pq+q^2=1 where R=p and r=q, but i'm not entirely sure how to go about this.
-Population practicies random mating (no picking your mates)
-No immigrration or emigration (i.e., a closed population)
Homework Answers
Allele Frequencies Equation:-
(p + q)2 =p2 + 2pq + q2
It must also be noted that the sum of all the allelic frequencies and of all the genotypic frequencies must always be 1. The Hardy-Weinberg law is applicable when there is random mating.
(0.1)^2 + 2(0.1*0.9) + (0.9)^2=1
0.01 + 2(0.9) + 0.81=1
0.01 + 1.8 + 0.81=1
2.62=1
0.62

Give the Hardy–Weinberg expected genotypic frequencies for an autosomal locus with three alleles, where the frequencies of alleles A1, A2, and A3 are defined as p, q, and r, respectively. Set the problem up and show your work. Tay–Sachs disease is an autosomal recessive disorder. Among Ashkenazi Jews, the frequency of Tay–Sachs disease is 1 in 3600. If the Ashkenazi population is mating randomly for the Tay–Sachs gene, what proportion of the population consists of heterozygous carriers of the Tay–Sachs...

Two people who are “carriers” of (heterozygous) for Tay Sachs disease marry and plan a family. What is the probability that a child from this union will suffer from Tay Sachs disease. (Recall that this is an autosomal recessive disorder, that is, homozygous recessives have the disease.) a. Zero b. 0.25 c. 0.5 d. 0.75 e. 1.0 6. At Hardy-Weinberg equilibrium, heterozygotes are the most common genotype in the population when- a. b. c. d . p> 0.67 q>0.67 and...

2.3 Problem 3 The Hardy-Weinberg equation is useful for predicting the percent of a hu- man population that may be heterozygous carriers of recessive alleles for certain genetic diseases. Phenylketonuria (PKU) is a human metabolic dis- order that results in mental retardation if it is untreated in infancy. In the United States, one out of approximately 10.000 babies is born with the disor- der. Approximately what percent of the population are heterozygous carriers of the recessive PKU allele? If you...

Plase hlp answer these questions:
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...

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...

1. You are studying a population of sandblossoms (Linanthus parryae) that has individuals with blue and white flowers. The allele for white flowers (A) is dominant to the allele for blue flowers (a). In the population you survey, 91 out of 100 individuals have white flowers. Based on this information: a. Calculate the frequency of the A and a alleles. b. Calculate the numbers of each genotype. 2. A population of snapdragons (Antirrhinum hispanicum) has two additive alleles for flower...

On the island of Notion, in the Factotum Archipelago, there lives a population of pencil bears. A portion of these bears have silky fur, and as a result, are much better surfers. The texture of the fur is determined by a single autosomal locus with two alleles: S (trait allele) and s (wild type allele). In a recent study, researched collected the values in the following table: Table 1. Counts of Pencil Bear fur style by genotype Phenotype Genotype Silky...
