PATHOLOGY

Detailed explanation-1: -A linkage map (also known as a genetic map) is a table for a species or experimental population that shows the position of its known genes or genetic markers relative to each other in terms of recombination frequency, rather than a specific physical distance along each chromosome.

Detailed explanation-2: -All genes are arranged linearly along the chromosomes. The nucleus of most human cells contains 2 sets of chromosomes, 1 set given by each parent. Each set has 23 single chromosomes22 autosomes and an X or Y sex chromosome. (A normal female will have a pair of X chromosomes; a male will have an X and Y pair.)

Detailed explanation-3: -A gene is a discrete linear sequence of DNA which corresponds to a heritable trait. In more general terms, one can think of genes as the smallest unit of heredity.
