Meiosis 1 Drawing

Meiosis 1 Drawing - Explain the differences between meiosis and mitosis. Describe and draw the key events and stages of meiosis that lead to haploid gametes. Web by the end of this section, you will be able to: Web in the circle below, sketch a 2n=6 diploid cell in metaphase of mitosis. Web meiosis, division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or sex cells, each possessing half the number of chromosomes of the original cell. Web meiosis is a type of cell division in which a single cell undergoes division twice to produce four haploid daughter cells. Describe cellular events during meiosis. The s phase is next, during which the dna of the chromosomes is replicated. These are prophase, metaphase, anaphase, and telophase. Meiosis is preceded by an interphase consisting of three stages.

22k views 3 years ago biology diagrams (class 11 & 12) thanks for watching! Prophase i, metaphase i, anaphase i, and telophase i. Meiosis involves two divisions, so it’s typically broken down into meiosis i and meiosis ii. Meiosis i and meiosis ii.

Web Meiosis I Takes Place, And There Are 2 Cells, Each With Only 4 Chromosomes.

Before a dividing cell enters meiosis, it undergoes a period of growth called interphase. The s phase is next, during which the dna of the chromosomes is replicated. Web in the circle below, sketch a 2n=6 diploid cell in metaphase of mitosis. For further discussion, see cell:

Explain The Differences Between Meiosis And Mitosis.

Prophase i is the first stage of meiosis i, followed by prophase ii, anaphase i, anaphase ii, metaphase i and metaphase ii. A monogenic gene gives rise to a trait from a single set of alleles. During prophase i, chromosomes pair up and exchange genetic material, creating more variation. The cells produced are known as the sex cells or gametes (sperms and egg).

There are two successive nuclear divisions: Be sure to label the centromere, centrioles, and spindle fibers. Likewise, meiosis ii (during which the second round of meiotic division takes place) includes prophase ii, prometaphase ii, and so on. Meiosis is preceded by an interphase consisting of three stages.
