Suppose that black hamsters were found to be 70% of the population and the gray hamsters 30% of the population. Calculate the percentage of BB, Bb, and bb hamsters in the next generation.
 I don't know how to calculate the percentage of the genotypes.

a google search showed:
This is a HardyWeinberg type question.
The population is composed of RR, Rr, and rr individuals.
To figure out genotypic frequencies, it's a matter of multiplying out the frequencies.
HardyWeinberg says that the population frequencies are RR: 2Rr : rr or RxR: 2 x R x r: r x r.
You have .7*.7:2*.7*.3:.3*.3
= .49 : .42 : .09
Not sure how this relates to the frequencies in the next generation . . .

BB (Homozygous dominent) 25% and Bb (heterozygous dominent) 50% and bb(homozygous recessive.so phenotypic ratio is 3:1 and genotypic ratio is 1:2:1
