Explanation:
When genes are found on different chromosomes or far apart on the same chromosome, they assort independently and are said to be unlinked.
When genes are close together on the same chromosome, they are said to be linked. That means the alleles, or gene versions, already together on one chromosome will be inherited as a unit more frequently than not.
We can see if two genes are linked, and how tightly, by using data from genetic crosses to calculate the recombination frequency
