What are the two distinct stages of meiosis?
Meiosis I and meiosis II
How is genetic material passed from parent to offspring in meiosis?
Meiosis is a form of cell division which is used in sexual reproduction. In other words, it is the process of making sperm/egg cells in genetic material. There is "meiosis I" which separates the homologues and then there is "meiosis II" which separates the sister chromatids. In meiosis I there are four stages to the division process: Prophase (which is where the homologue chromosomes start to condense), Metaphase (which is where the chromosomes begin to align in the center of the cell), Anaphanse (which is the when the chromasomes start to separate in half) and Telophase (where the resulting chromosomes begin to break off into two separate cells). Meiosis II has a very similar process which ultimately divides the two newly separated cells into a total of four cells (all with their own variation of genetic material). Be sure not to confuse this process with "mitosis", which is the cell division and production process that occurs in asexual reproduction.
How does prophase you of meiosis differ from prophase of mitosis?
a. chromatids do not separate at the centromere in anaphase I. b. centromeres do not exist in anaphase I. c. crossing-over occurs only in anaphase of miitosis
What is the difference between anaphase 1 and anaphase 2 in meiosis?
Hello, Anaphase 1 and 2 are both part of the process of meiosis, the division of sex cells, and they are both phases where chromosomes are being pulled apart by the centrioles. However, in anaphase one the chromosomes are lined up in homologous pairs, meaning that there are two chromosomes side by side, so when the centrioles pull they are separating two unconnected chromosomes. In anaphase two the chromosomes are lined up in single file. So the centrioles are pulling one chromosome apart. It eventually breaks the link at the centromere of the chromosome and results in two sister chromatids. Hope this is clear enough to understand!
In the process of cellular respiration carbohydrate combines with what to produce carbon dioxide and what and energy?
i) O2, & ii) H2O.
What occurs in meiosis i that does not occur in meiosis ii?
DNA is copied.
When does an oocyte complete meiosis II?
Meiosis II is completed after entry of sperm.
Is there a replication step before meiosis ii?
Yes, there is no replication step between meiosis I and meiosis II. The DNA remains in a duplicated state from the end of meiosis I and goes directly into meiosis II, where the sister chromatids are separated.
Meiosis consists of two cell divisions what are they?

DNA replication occurs?
The Replication of DNA does occur before the cell can divide.
Is cytokneisis a step of meiosis?
No. Cytokinesis and mitosis are the two different steps of cell division. (Keep in mind that mitosis comes first.)
What stage of meiosis is the ovulated egg stopped?
The ovulated egg is stopped at metaphase II of meiosis. At this stage, the egg is arrested until fertilization occurs.
Meiosis II is similar to which process?
Meiosis II is identical to Mitosis. Meiosis is split into two stages, Meiosis I and Meiosis II. Meiosis I is similar to mitosis however the cells resulting from it have half as many chromosomes as the parent cell.
How many times does meiosis occur in a human?
Remember that meiosis occurs during the production and maturation of gametes so it occurs very often! In males, it occurs virtually throughout their whole life and in females, meiosis I completes at every ovulatory cycle until menopause and meiosis II completes with fertilization.
Are Meiosis I and Meiosis II identical steps that follow each other?
If you mean meiosis I and meiosis II, then no they are not identical, but meiosis II does follow meiosis I.
What is process of meiosis?
Meiosis is a type of cell division that is necessary for the animals, plant, and fungi sexual reproduction. In this process the meiosis are divided into two divisions the meiosis I and meiosis II and the each division has four stages: prophase, metaphase, telophase and anaphase.
What is interkinesis?
Interkinesis or interphase II is a period of rest that cells enter during meiosis. It is the abbreviated interphase that occurs between meiosis I and II. No DNA replication occurs during this stage of Meiosis. Many plants skip telophase I and interkinesis, going immediately into prophase II. Each chromosome is still composed of two chromatids.
