Meiosis
Where does crossing over and synapsis occur?
Both ONLY occur during Prophase 1 in Meiosis
What cells are going to become eggs during Oogensis?
Cells of the Ovary (oognonia)
What cells are going to be turned into sperm cells?
cells of testes (spermatogonia)
Both Meiosis and Mitosis undergo DNA replication?
True or False
True
What gets separated during Telophase 2 by the spindle fibers?
Sister chromatids
What stage of Meiosis are arrested until puberty during oogenesis?
Prophase 1
Do sperm cells get arrested at any point during spermatogenesis?
No, only ovary cells get arrested
How do Metaphase in Mitosis and Metaphase 1 in Meiosis
In Mitosis chromatids are pulled apart, In Meiosis 1 tetrads are separated
What is a group of 4 chromosomes attached called? and what is the proccess called?
Tetrads, Pair of Homologous chromosomes, or Bivalents
(all mean the same thing)
Synapsis: Formation of the Tetrads or Bivalents
How many ovum are produced during 5 cycles of Oogenesis
5
How many sperm cells will be the product of 8 cycles of spermatogenesis?
32 sperm cels
Daughter cells produced from Meiosis are diploid
True or False
False, daughters produced from Meiosis are haploid
What is the purpose of crossing over and what is the region called where crossing over occurs?
The purpose of crossing over is to increase genetic diversity. (four different daughter cells)
Crossing over occurs at the Chiasma/Chiasmata
What stages of Meiosis does not occur until feralization of the egg cell?
Anaphase 2 and Telophase 2 and Cytokinesis
What process do spermatids go through to become sperm?
Differentiation
Synapsis and crossing over occurs in Mitosis during Prophase.
True or False
False
List proccess' that Meiosis undergoes that Mitosis does not.
Tetrads formed through Synapsis
Crossing over to increase variation
Chiasma/Chiasmata forms for Crossing over
Tetrads separate during Telophase 1 instead of chromatids
Chromatids separate during Telophase 2 like mitosis
Name all cells involved during Oogenesis in order of division.
Germ Cell > Oogonium (ovary cells) > Primary Oocyte and 1st Polar Body > Secondary Oocyte > Ovum and Polar bodies
Name all cells involved during Spermatogenesis in order of division.
Germ Cell > Spermatogonia > Primary Spermatocyte > Secondary Spermatocyte > Spermatids > Sperm
Are daughters in Mitosis identical or different?
Identical
