What happens during Interphase?
Interphase is where a cell grows, replicates its chromosomes, and prepares for cell division.
100
What is Oogenesis and its purpose?
The process of formation of female gametes. This process begins inside the fetus before birth.
100
What stage is Anaphase?
The 4th Stage
200
What are the stages of Interphase?
G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth).
200
What happens to the chromosomes in Prophase 1?
The homologous chromosomes condense and become visible as the x shape we know, pair up to form a tetrad, and exchange genetic material by crossing over.
200
What is Spermatogenesis and its purpose?
Spermatogenesis is the process by which sperm cell production occurs; the germ cells give rise to the haploid spermatozoa.
200
Name this phase of meiosis?
Anaphase 1
200
How many Chromosomes are there at the end of Telophase 2?
23 chromosomes
300
What happens during the S Phase?
S phase is the period of wholesale DNA synthesis during which the cell replicates its genetic content
300
What happens during Prophase 2?
During prophase II, the chromosomes condense, and a new set of spindle fibers forms.
300
What is important about Anaphase?
Anaphase makes sure that each cell has an equal number of chromosomes.
300
What happens in cytokinesis?
Daughter cells separate completely as cytoplasm is split into two
400
What is the diffrence between Prophase 1 & 2?
Prophase I involves the separation of homologous chromosomes while prophase II involves the separation of sister chromatids.
400
What step in mitosis is after the one shown in the image?
Metaphase
400
What happens If chromosomes fail to separate properly during Anaphase?
Has an abnormal number of chromosomes.

1 Simple/Key Diffrence between Meiosis & Mitosis
Mitosis produces two genetically identical “daughter” cells from a single “parent” cell, whereas meiosis produces cells that are genetically unique from the parent and contain only half as much DNA
