Using the example of pea color in Mendel’s pea plants, can you devise equations to determine the allele frequencies of A and a from the genotype frequencies of aa, Aa, and AA?
In radish the effect of the alleles producing the red long variety is incompletely dominant over the effect of the alleles producing the white round variety; the heterozygote being purple oval.
(Answer should be written in ratios only, for example: 1:2 or 1:2:3 or 1:2:3:4, etc... DO NOT place any space between numbers and colons. All answers must be in the lowest terms.)What genotypic ratio would you expect in a cross between radishes that are:Red, long x white, round?

- 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.
