Expert Answer

Step 1

Linkage is defined as the transmission pattern of genes when they are present on the same chromosome.  These genes are called linked. Since these genes are present together, their distribution into gametes occurs together. They may be present on the autosomes or sex chromosomes. There are 24 linkage groups (22 pair of autosomes + 1 X chromosome + 1 Y chromosome) in males, and 23 linkage groups (22 pairs of autosomes + 1 pair of X chromosome) in females.

Step 2

During gamete formation, event of recombination happens between homologous chromosomes. The shorter the distance between two genes, the lesser are the chances of chiasma formation/recomb...
