What is used to make a linkage map for a group of organisms?

the number of phenotypes a gene set can produce in the group

the number of traits one gene set can control in the group

the number of times linked genes are separated in the group

the number of different genes found in the group

To make a linkage map for a group of organisms, the key factor is to analyze the frequency of recombination between genes. Recombination data is used to determine the relative positions of genes on a chromosome and construct a linkage map.

So which answer
