Detailed explanation-1: -What are chromosomes? Human genetic information isn’t encoded on just one strand of DNA. A cell nucleus contains a number of strands. These strands are called chromosomes.
Detailed explanation-2: -Genetic information is passed from generation to generation through inherited units of chemical information (in most cases, genes). Organisms produce other similar organisms through sexual reproduction, which allows the line of genetic material to be maintained and generations to be linked.
Detailed explanation-3: -Crossing over, as related to genetics and genomics, refers to the exchange of DNA between paired homologous chromosomes (one from each parent) that occurs during the development of egg and sperm cells (meiosis).
