Meiosis Flashcards
1
Q
Define Meiosis
A
Reductive division = genetically distinct haploid gametes
2
Q
What occurs in Meiosis I?
A
Parent cell DNA replication
Genetic recomb/cross over
Exchange portions of chrms btwn maternal + paternal-derived chrms of homologous pair
3
Q
When does crossing-over of chromosomes occur?
A
Prophase of Meiosis I
4
Q
Explain independent assortment of Meiosis I
A
2^n diff types
N = # chrms
Results in 2 genetically diff progeny cells
5
Q
What step does Meiosis II lack? What does it resemble?
A
No DNA replication
Resembles Mitosis = 4 haploids, genetically distinct progeny cells
