Review of Lecture 17: All together now: Chromosomes.

1. Discovery of chromosomes and rediscovery of Mendel led to Chromosomal Theory of Inheritance

2. Meiosis - 1) reduction division; 2) introduction of genetic variation through crossing over

3. Alternation of generations: diploid to haploid; 2n to 1n; meiosis

4. Mitosis vs. meiosis

5. Homologue; homologue pairs; crossing over; what happens to each individual chromosome of a homologue pair?

6. Linkage; incomplete linkage; crossing over; mapping studies (crosses to see what traits combined; associated with linkage groups (chromosomes)
