The answer is Diploid number of Chromosomes, Haploid number of Chromosomes and Gamete Cells.
Explanation:
Meiosis is one of the forms of cell reproduction, this process is performed in the gonads for the production of gametes (haploid sex cells). Meiosis is a process of cell division in which a diploid cell (cells that have a double number of chromosomes) experiences two successive divisions, with the ability to generate four haploid cells.
By finding recombination frequencies for many gene pairs, we can make linkage maps that show the order and relative distances of the genes on the chromosome ..
