Comparing mitosis + meiosis Flashcards
1
Q
How many chromosomes does mitosis have?
A
46
2
Q
How many chromosomes does meiosis have?
A
23
3
Q
Is DNA replication needed for cell division in both?
A
Yes
4
Q
How many daughter cells does mitosis produce?
A
2 - diploid
5
Q
How many daughter cells does meiosis produce?
A
4 - haploid
6
Q
What are the functions of mitosis?
A
- Growth
- Repair
- Division of cells
- For asexual reproduction
7
Q
What are the functions for meiosis?
A
- Produces gametes
- Division
- Reduces chromosomes
- For sexual reproduction
8
Q
What are the advantages of meiosis over mitosis?
A
- Produces haploid num in gamete cells
- Allows mixing of genetic material in new generation
- Introduces variation within species
Without meiosis, only variation possible is due to mutation
9
Q
What is the genetic composition of the daughter cells in mitosis + meiosis?
A
Mitosis = Genetically identical to parent cell
Meiosis = Genetically different to parent cell
