Genetics - Linkage and Recombination

Questions from reading quiz 6

What is the primary difference between linked genes and genes that assort independently?

Linked genes are close together on the same chromosome and do not follow independent assortment.

What is a centimorgan (cM), and how is it used in genetic mapping?

A unit of measurement indicating 1% recombination frequency between genes

If two genes have a recombination frequency of 50%, what can you conclude about their physical location on the chromosome?

They are on different chromosomes or far apart on the same chromosome

In a test cross, you observe 120 recombinant offspring out of a total of 500 offspring. What is the recombination frequency between the two genes?

24%

Which of the following best describes the relationship between recombination frequency and physical distance between genes?

Recombination frequency increases as physical distance between genes increases
