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)?
For 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.

- 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_forwardA wild-type fruit fly (heterozygous for gray body color andred eyes) is mated with a black fruit fly with purple eyes.
