How does meiosis lead to variation?

Define Homologous Chromosome

Homologous chromosomes are chromosome pairs of the same length,

centromere position, and staining pattern with genes for the same

characteristics. One homologous chromosome is inherited from the organism's

mother, the other from the organism's father

Outline the process of Meiosis…

Meiosis includes two rounds of division: Meiosis I, Meiosis II.

Meiosis I Prophase I, Metaphase I, Anaphase I and Telophase I.

Homologous chromosomes are paired

While paired, they cross over and exchange genetic information (DNA)

Homologous pairs are then separated, and two daughter cells are produced

Meiosis II Prophase II, Metaphase II, Anaphase II and Telophase II.

the same as mitosis

sister chromatids of each chromosome separate

result is four haploid daughter cells

Task
