1. You survey a population of minnows in Hardy-Weinberg equilibrium
and find that there are three different genotypes; Red, Purple, and Blue fins. The genotypes for Red (RR), Purple (Rr), and Blue (rr) fins have different survival rates at 0.7, 0.8, and 0.5, respectively. The size of the population does not decrease from generation to generation and all individuals lost to selection are replaced by new individuals being born. If the population starts with 30 Red, 30 Purple, and 40 Blue fins, what is the expected number of individuals of each genotype in the next generation (round to nearest whole individual)? Clearly show each step of your work.
