Suppose that in studies of genes on the same chromosome, you find the following recombination frequencies: a 40% frequency for a and b, a 30% frequency for a and c, and a 10% frequency for b and C Which phrase best describes the relationship between genes a, b, and c?

Question

Quizplus · Accepted Answer

The fact that recombination frequencies less than 50% between genes a and b, a and c, and b and c suggest that these genes are located on the same chromosome and are therefore linked. The frequencies suggest that gene a is located between genes b and c, but do not necessarily provide information about whether these genes are alleles of the same gene or different genes.
