1. WARM UP
List anything and everything you know about chromosomes, mitosis, meiosis, or cell division.

2. Chromosomal Inheritance

3. Chromosomes DNA coiled on proteins Humans have 46 22 pairs XY pair
Homologous pairs
Alleles of genes
Humans have 46
22 pairs
XY pair

4. Karyotype Shows # of chromosomes and their shape
Can determine mutations

5. Inheritance Parents = 23 pairs 23 chromosome sex cell Fertilization
Meiosis
Fertilization
Genetic recombination
Offspring = 23 pairs
1 from each parent

6. Meiosis Forms variety of parental sex cells Crossing over Segregation
Independent assortment

7. Hereditary Evolution
New traits form or frequencies change as meiosis and fertilization create variety
Mutations
Natural selection
Speciation

8. WRAP UP
Explain the process of meiosis, including the names of all 8 steps and at least 3 words to describe each of those steps.
