There are two types of alleles:
Type B1 and Type B2
(In total there are 10)
Type B1 has 6
Type B2 has 4
Question:
What is the probability of an individual in the offspring generation being homozygous [p^2] for B1?
What is the probability of an individual in the offspring generation being homozygous [q^2] for B2?
What is the probability of an individual in the offspring gen being heterozygous[2pq]?
What is the frequency of the heterozygous genotype if the homozygous genotype frequencies are 0.1385 (BB) and 0.5897 (bb)?
In a population of 100 pea plants, there are two variations for flower color--purple and white. After counting, the nymber of white plants were 9 plants. What would be the number of plants that are heterozygous (2pq)?

- Using the HardyWeinberg Law in Human Genetics Suppose you are monitoring the allelic and genotypic frequencies of the MN blood group locus (see Question 2 for a description of the MN blood group) in a small human population. You find that for 1-year-old children, the genotypic frequencies are MM = 0.25, MN = 0.5, and NN = 0.25, whereas the genotypic frequencies for adults are MM = 0.3, MN = 0.4, and NN = 0.3. a. Compute the M and N allele frequencies for 1-year-olds and adults. b. Are the allele frequencies in equilibrium in this population? c. Are the genotypic frequencies in equilibrium?arrow_forwardFor the purpose of the assignment, we will refer to XY individuals as male and XX individuals as female. In humans, colorblindness (b) is an example of an X-linked recessive trait. In this problem, a male with colorblindness XbY marries a female who is not colorblind but is a carrier of the colorblindness allele (XXb). Using a Punnett square, determine the genotypic and phenotypic probabilities (as percentages) for their potential offspring. Give the percentages in numbers, without the percent sign, for each genotype and phenotype. Genotypes XX Xxb xbxb XY xby Phenotypes Consider females (XX) individuals only. In the two questions below, I am asking for the % of females, not % of all people. What is the % of females who are not colorblind? What is the% of females who are colorblind?
