Question

What information about recombination frequencies enables scientists to create linkage maps?

Answer 1

The answer is;

1. The recombination frequency is proportional to the distance between the two genes
2. The lower the recombination frequency, the farther apart two genes are on the chromosome

Genes that are close together are more likely to be passed together to offspring during recombination. Geneticist compares the ration between the proposed phenotype offspring and actual phenotype offerings in a population. The higher the recombination frequency (centimorgans," or cM), the closer the genes are linked together, physically.
