What is segregation |
To seperate |
|
|
What is Chiasmata |
To cross over |
|
|
What is prophase 1 |
Chromosomes thicken and n.e dissolved |
|
|
What is telophase 2 |
N.e reformed and random selection of haploid, genetic variation |
|
|
What is prophase? |
Chromosomes thicken and n.e dissolves |
|
|
What is metaphase? |
Spindle fiber forms, moves to middle |
|
|
What is anaphase |
Goes from two end to one end, they pull apart |
|
|
What is telophase? |
N.e reforms, cell membrane starts to divide |
|
|
What is cytokinesis? |
A complete n.e and complete cell membrane |
|
|
What is Interphase? |
Duplicates itself, they growth in synthesis |
|
|
What is centromere? |
It is the middle part of wings |
|
|
What are chromatids? |
It is when DNA protect this, uses wings |
|
|
What comes first during meiosis I? |
Prophase 1 |
|
|
What is Metaphase 1 |
Second event of meiosis I, spindle fiber forms, they lined up in the middle |
|
|
What is the third event during Meiosis I? |
Anaphase I |
|
|
What is Anaphase I? |
Diploids got pulled away |
|
|
What is Telophase I? |
New cells split apart, nuclear envelope reforms |
|
|
What is Prophase II? |
First event in Meiosis II, n.e dissolves and chromosomes denses |
|
|
What is Metaphase II? |
Spindle fiber forms, chromosomes lined up in the middle |
|
|
What is Anaphase II? |
Goes from two end to one end, opposite sides of the cells that pulls apart |
|
|
What are 2 ways that meiosis creates genetic variation? |
They cross over from Prophase 1, random selection of haploids from Telophase 2 |
|
|
What are the two events during mitosis? |
Chromosomes divide, growth in repair |
|
|
What two events occur during homologous chromosomes? |
Separates in Meiosis 1, they are similar but not identical |
|
|
What two events occur during sister chromatids? |
They divide in Meiosis 2, two copies of the same chromosome s |
|
|
What happens during chromosome structure? |
Condense during mitosis, makes chromatids called dna |
