Question

How do you find the distance between two genes?

Answer 1

Distance between two genes

1. Two genes are said to be linked when they are found on the same chromosome.
2. That means that alleles, or gene versions, that are already present on one chromosome will be inherited as a group more often than not.
3. We can determine whether and how closely two genes are linked by calculating the recombination frequency using data from genetic crosses.
4. We can create linkage maps that show the order and relative distances of the genes on the chromosome by determining recombination frequencies for many gene pairs.
5. A linkage map (also known as a genetic map) is a table for a species or experimental population that shows the position of known genes or genetic markers in terms of recombination frequency rather than a specific physical distance along each chromosome.
