👉 Chromosomic refers to the process of comparing two individuals and determining their genetic makeup. In this context, it involves examining the chromosomes that make up an individual's genome, which are the DNA strands that contain the instructions for the cell's structure and function. Chromosomes can be divided into two main types: autosomes (which carry the sex-linked genes) and sex chromosomes (which carry the sex-tract genes). By comparing these two sets of chromosomes, scientists can determine the sex and genetic
