Gametogenesis Cellular Reproduction Cell theory states that all cells arise from other cells. The primary means of producing body cells is the process of mitosis . Mitosis occurs in most body cells at one time or another and produces two genetically identical daughter cells. In contrast, meiosis occurs only in the germ cell line and produces gametes . Unlike mitosis, which results in two identical diploid cells, cells completing meiosis undergo two rounds of cell division and theoretically gives rise to four non-identical

Unformatted text preview: haploid cells. These cells are non-identical because of the Mendelian genetic principles of independent assortment and segregation and the meiotic process of recombination . Thus, when a gamete from each parent combines during sexual reproduction , each gamete contributes 23 modified parental chromosomes and the resultant offspring has the normal chromosomal complement of 46 chromosomes in their cells (see Figure 1). Therefore, offspring have genetic material from both parents. Figure 1...
