At k-th generation, calculate the probability that there are at least n organisms with AaBb genotype." { $nl "" }
"The code uses the fact that each organism at any generation has exactly 1/4 chance of being an AaBb. Polynomial power gives a sequence where i-th value is the chance of having exactly i AaBb's in the population." } ;
