11.1: The Process of Meiosis - Introduction to Meiosis
-
Meiosis is the nuclear division of diploid cells into haploid cells, which is a necessary step in sexual reproduction.
-
-
11.2: The Process of Meiosis - Meiosis I
-
In meiosis I, the first round of meiosis, homologous chromosomes exchange DNA and the diploid cell is divided into two haploid cells.
-
-
11.3: The Process of Meiosis - Meiosis II
-
During meiosis II, the sister chromatids within the two daughter cells separate, forming four new haploid gametes.
-
-
11.4: The Process of Meiosis - Comparing Meiosis and Mitosis
-
Mitosis and meiosis share some similarities, but also some differences, most of which are observed during meiosis I.

11.5: Sexual Reproduction - Advantages and Disadvantages of Sexual Reproduction
-
The genetic diversity of sexual reproduction, observed in most eukaryotes, is thought to give species better chances of survival.

11.6: Sexual Reproduction - Life Cycles of Sexually Reproducing Organisms
-
The main categories of sexual life cycles in eukaryotic organisms are: diploid-dominant, haploid-dominant, and alternation of generations.
