If you go to you. tube then go search Never Gonna Give You Up and click on the first video, It helps explain my question :)

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.

What is the distance between (–2 1/2,-3) and (1, –3)?

X+ y = 5 ; x - y =3 solve using linear combination
