Meiosis 2 Flashcards
1
Q
Meiosis II Overview
A
- Focuses on second stage of meiosis.
- Follows meiosis I.
- Aims to separate chromatids and create haploid cells.
2
Q
Prophase 2
A
- Two separate cells after meiosis I.
- No crossing over occurs.
- Homologous pairs are now in separate cells.
3
Q
Prophase 2 Purpose
A
- Spindle fibers form.
- Centrioles move to opposite poles.
- Chromosomes are no longer homologous partners.
4
Q
Prophase 2 Identification
A
- No crossing over.
- Recombinant chromosomes with visible recombination.
- Spindle fibers forming.
5
Q
Metaphase 2
A
- Chromosomes move to equator.
- Spindle fibers attach to centromeres.
- Chromatids need to be separated.
6
Q
Metaphase 2 Purpose
A
- Random arrangement of recombinant chromosomes.
- Individual chromosomes at the equator.
7
Q
Metaphase 2 Identification
A
- Double-stranded chromosomes at the equator.
- Spindle fibers attached to centromeres.
8
Q
Anaphase 2
A
- Chromatids separate into individual chromosomes.
- Chromosomes move to opposite poles.
9
Q
Anaphase 2 Purpose
A
- Separate recombinant chromosomes.
- Form single-stranded chromosomes.
10
Q
Anaphase 2 Identification
A
- Spindle fibers contracting.
- Single-stranded chromosomes.
11
Q
Telophase 2
A
- Nuclear membrane reforms around sets of chromosomes.
- Cytokinesis pinches off cytoplasm, forming four cells.
12
Q
Telophase 2 Identification
A
- Four non-identical cells.
- Single-stranded chromosomes.
13
Q
Summary Of Meiosis 1 and 2
A
- Meiosis I reduces chromosome number.
- Meiosis II separates chromatids, forming haploid cells.
14
Q
Terminology Recap : Random arrangement
A
Chromosomes at equator.
15
Q
Terminology Recap : Cytokinesis
A
Separation of cytoplasm.
