Assume that a population of 50 individuals has the following numbers of genotypes for a gene with two alleles, b and b: bb = 30, bb = 10, and bb = 10. calculate the frequencies of the two alleles in the population’s gene pool.

Write the equation in logarithmic form m^x=n

Xy x xy if a and b are positive integers such that a*b=9 and b*a=72 what is the value of a/b
