Define each: Meiosis: Gamete: Diploid: Haploid: Key terms: meiosis, diploid, haploid, homologous, chromosomes.

2 How does meiosis lead to variation?
Objectives Outline the basic principles and process of meiosis. Define homologous chromosomes. Outcomes 3: Outline the stages of meiosis. 5: Describe the stages of meiosis. 7: Fully explain the process of meiosis. Key terms: meiosis, diploid, haploid, homologous, chromosomes.

3 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

5 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
