Outline of course

• Genetic continuity between generations of cells and between generations of sexually reproducing organisms is maintained through the processes of mitosis and meiosis, respectively. • Diploid eukaryotic cells contain their genetic information in

pairs of homologous chromosomes, with one member of each pair being derived from the maternal parent and one from the paternal parent.

(3)

Outline of course

• Mitosis converts a diploid cell into two diploid daughter cells. • The process of meiosis distributes one member of each

homologous pair of chromosomes into each gamete or spore, thus reducing the diploid chromosome number to the haploid chromosome number.

• Meiosis generates genetic variability by distributing various combinations of maternal and paternal members of each homologous pair of chromosomes into gametes or spores.

Spermatogenesis is the process, in which spermatozoa are produced from male primordial germ cells by way of mitosis and meiosis.. Oogenesis is the process of development of

• Results of this division, from the secondary oocyte occur to mature egg cell (ovum) with haploid chromosome and the second polar body (polosit II).. • Thus, at the end of

 Mitosis leads to the production of two cells, each with the same number of chromosomes as the parent cell..  Meiosis reduces the genetic content and the number of chromosomes

• Crossing over between homologs during meiosis creates recombinant gametes with different combinations of alleles that enhance genetic variation.. • Crossing over between
