Question

What is an example of linkage (organism, chromosome number, genes)?

Answer 1

Only genes can remain as 'linked'.

Explanation:

On the length of a chromosome, genes are linearly arranged. The location of genes on a single chromosome with respect to one another could be depicted by a linkage map.

The genes on different chromosomes can show independent assortment but genes closely placed on same chromosome would tend to move together during gamete formation, a phenomenon known as 'linkage'.

Less gap between two genes on same chromosome means there is more possibility of these entering together in a gamete.
