1
Product of Meiosis (include number of cells, type of cells, number of chromosomes, and how it looks)
4 haploid, genetically unique, gametic cells
1
Mutations in this cell type will be passed to offspring
Gametic Cells
1
The two events of meiosis that increase genetic diversity
Crossing-Over and Independent Assortment
1
When does crossing over occur?
Prophase I
1
What type of mutation has occurred?
ORIGINAL DNA: TAC GGA AAA CAC
MUTATED DNA: TAC GGA AAA ACA C
Insertion
2
Look at the codon chart. Explain how a silent mutation is possible. Give an example.
Multiple codons code for the same amino acids
EX: CCC codes for proline, CCG also codes for proline
2
What is the impact on chromosomes during meiosis?
Chromosome Reduction
2
What type of mutation has occurred?
ORIGINAL DNA: TAC GGA AAA CAC
MUTATED DNA: TAC GGA AAC AC
Deletion
2
The term used to describe a cell with 2n sets of chromosomes
Diploid
2
Explain Crossing Over
Portions of homologous chromosomes swap places during Prophase I
3
What type of mutation has occurred?
ORIGINAL DNA: TAC GGA AAA CAC
MUTATED DNA: TAC GGG AAA CAC
Substitution
3
The term used to describe a cell with n sets of chromosomes
Haploid
3
A change in one nitrogen base
Point/Substitution
3
Why is crossing over important during meiosis?
Increases the genetic diversity
