...will be 50%% when there is always one crossover between them. But what if there are some meioses with a double crossover? These will also produce the 4 gametic types in equal frequencies. Why? Because there are three types of double crossovers: two-strand doubles, three- strand doubles, and ... enough apart that there is a least one crossover between them in 100%% of the meioses they ...
