Answer #1

Frequency of red allele (p) = 0.46

According to HWE

p+q = 1

q = 1-p = 1-0.46 = 0.54

p2 + 2pq + q2 = 1

p2 + 2pq = frequency of red phenotype

q2 = frequency of white phenotype

Frequency of red phenotype = p2 + 2pq

= (0.46)2 + 2*0.46*0.54

= 0.21 + 0.49 = 0.70

    A population of pea plants may have white flowers (the dominant phenotype) or yellow flowers (the recessive phenotype). The frequency of homozygous dominant individuals is 0.63. Answer the questions below. For each, type out the equation with the appropriate numbers filled in as well as the answer. How would you calculate the frequency of the white homozygous alleles? How would you calculate the frequency of the recessive alleles? How would you calculate the frequency of the heterozygous individuals?

    In wild petunias, the allele for red flower color (R) is dominant over the allele for white flower color (r). We sample a population and find 750 plants have white flowers and 270 have red flowers. If the population is in HWE, what are the allele frequencies of R and r in this population? How many of the 270 plants that have red flowers are homozygous and how many are heterozygous at the flower color locus? Show your work and...

    In wild petunias, the allele for red flower color (R) is dominant over the allele for white flower color (r). We sample a population and find 240 plants have white flowers and 85 have red flowers. If the population is in HWE, what are the allele frequencies of R and r in this population? How many of the 85 plants that have red flowers are homozygous and how many are heterozygous at the flower color locus?

    In a flowering plant, red flowers are dominant over white flowers, and short plants are dominant over tall plants. A short plant with red flowers was self-fertilized and the phenotypes for the resulting progeny recorded (see below). Based on the observed numbers, you propose the hypothesis that this dihybrid cross follows a 9:3:3:1 phenotypic ratio, whereby Mendel's laws apply. Based on this hypothesis, you calculated the expected number of progeny for each phenotype (see below). Phenotype Observed Number of Plants...

    The occurrence of the NN blood group genotype in the US population is 1 in 400, consider NN as the homozygous recessive genotype in this population. You sample 1,000 individuals from a large population for the MN blood group, which can easily be measured since co-dominance is involved (i.e., you can detect the heterozygotes). They are typed accordingly: BLOOD TYPE GENOTYPE NUMBER OF INDIVIDUALS RESULTING FREQUENCY M MM 490 0.49 MN MN 420 0.42 N NN 90 0.09 Using the...

    In a population, the melanic, black-colored seagull, is due to a dominant allele. Mm and MM individuals are black, and mm individuals are white. In each population, 81 individuals are white-colored, with 19 black- colored individuals. Assuming HWE, what is the approximate frequency of the melanic (M) allele in the population? In class, we took the square root of .81 to get the frequency of the recessive allele, but I don't know how that could be the frequency of the...
