7 DNA structure/replication and Mitosis + 8 Meiosis & Mendelian Genetics

1. Know the characteristics of meiotic prophase, metaphase, anaphase, and telophase and know what is different from meiosis I and II.

see http://www.dnaftb.org/dnaftb/8/animation/fs.html

2. What symbols do you put into Punnet squares and what do they represent?

3. What is the difference between a chromosome and a chromatid?

4. At what stage of meiosis do chromatids separate?

5. Explain why it is easier to establish genetically uniform ("pure bred") colonies of plants or animals with homozygous recessive traits.

6. For the upcoming lab (8) what is a "dihybrid cross"?

7. What is a pedigree?

8. What does it mean when a characteristic is "sex-linked"?
