1. Chapter 10 Meiosis and an INTRODUCTION to GENETICS Making Sex Cells (Gametes) and Genetics MHS Biology 2015

2. Chapter 10 Overview Section 10.1 What is the Process of Meiosis? Why is it Important? Section 10.2 What is Genetics? Who is Gregor Mendel and How is he important in understanding how traits are inherited? Section 10.3 How is Genetic recombination important for variety? How can genes be mapped on a chromosome?

5. Chart comparing Mitosis and Meiosis MitosisMeiosis One division = 2 cellsTwo divisions = 4 cells DNA replication occurs in interphase DNA replication before first division also in interphase SYNAPSIS does NOT occurSYNAPSIS DOES occur 2 Identical Cells formed that are DIPLOID (2n) Four unique Haploid cells are formed (1n) Only in BODY (Somatic) Cells Only in reproductive cells (Gametes) Mitosis is for GROWTH and REPAIR Meiosis is for REPRODUCTION of the species

6. Sexual Reproduction vs. Asexual Some organisms do NOT use gametes or specialized cells to reproduce. This is done through other means such as binary fission, propagation, cloning and parthenogenesis which were mentioned during the mitosis chapter.

10. Create a flipchart for your terms Using a sheet of paper create a vocabulary 16 page book which shows your understanding of the terms in Section 10.2 Define the term as well as illustrate or use appropriately in a sentence.

11. 10.2 Practice Punnett Squares Follow this link to punnett squares review.punnett squares Now complete the worksheet provided by completing your OWN punnett squares and determining the probability or likelyhood of getting certain offspring.

12. 10.3 Gene Linkage and Gene Mapping Some genes that are closer together are more likely to be inherited together but crossing over is more likely to occur between genes that are FARTHER apart. Click on links in the text above.crossing over FARTHER Maps of Chromosomes can actually show where specific genes are and also can gene LINKAGE maps can be created to show which traits often are expressed TOGETHER.
