ROUSes (Rodents of UNusual size) are either black or brown, Their color is determined by a single gene with two alleles: one that codes for black and the other for brown. The brown allele (b) is recessive to the black allele (B). You sample 100 ROUSes in a population and count 49 brown ones and 51 black ones. Assuming your sample is representative (an accurate reflection of the general population), how many of the black ROUSes are expected to be heterozygous if the population is in HardyWeinberg equillibrium? .
