Choose the statement that best describes the difference between mitosis and meiosis Mitosis is UNEQUAL division; meiosis is EQUAL with genetic variation. Mitosis separates linked genes; meiosis separates unlinked, independently assorting genes. Mitosis is EQUAL division without genetic variation; meiosis is reduction division with genetic variation. Mitosis requires one S phase; meiosis involves two S phases, one for each division.

Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:

- What are some of the key differences between mitosis and meiosis? Select all that apply. Reduction division occurs in meiosis only. Mitosis produces four daughter cells and meiosis only produces two. Gametogensis occurs in mitosis only. Meiosis produces four daughter cells and mitosis only produces two. Mitosis produces cells that are genetically identical to the parent cell whereas meiosis produces cells that only have half the genetic material of the parents. Both Mitosis and meiosis produce cells that are genetically identical to the parent cell.Which of the following statements does BEST compare the processes of mitosis and meiosis? Group of answer choices Mitosis involves two division cycles and results in haploid gametes, while meiosis consists of one division cycle and results in a diploid daughter cell Mitosis involves two division cycles and results in diploid daughter cells, while meiosis consists of one division cycle and results in haploid gametes. Mitosis involves one division cycle and results in diploid daughter cells, while meiosis consists of two division cycles and results in haploid gametes. Mitosis involves one division cycle and results in haploid gametes, while meiosis consists of two division cycles and results in diploid daughter cells.For each statement below, select mitosis if that statement is true only for mitosis.

- Though the stages of meiosis have the same names as the stages of mitosis, they exhibit fundamental differences. What are the main differences between the two processes? Meiosis differs from mitosis in that the number of chromosomes is halved and genetic variation is introduced in meiosis, but not in mitosis Meiosis differs from mitosis in that the number of chromosomes is halved and genetic variation is reduced in meiosis, but not in mitosis. Metaphase and telophase portions of meiosis and mitosis are the same. Meiosis and mitosis are also the same, except for the number of chromosomes. Anaphase I and anaphase are different. Prophase and telophase portions of meiosis and mitosis are the same. Meiosis II and mitosis are also the same and have the same number of chromosomes. Anaphase I and anaphase are different.Which of the following statements about mitosis and meisois are TRUE? (check all that apply) Mitosis produces genetically identical cells, whereas meiosis produces genetically variable (different) cells. Mitosis consists of a single nuclear division, whereas meiosis consists of two nuclear divisions. DNA replication occurs prior to mitosis and meiosis I. Crossing over occurs in both meiosis I and meiosis II. The number of chromsoomes in newly formed cells is the same as the mother cell in both mitosis and meiosis. 00000Table below presents the criteria to be used in comparing mitosis and meiosis.

O It has twice the DNA of the cell that began meiosis. O It has one-fourth the DNA and one-half the chromosomes as the cell that began meiosis II. O It has the same amount of DNA at the beginning and end of Meiosis II It has half the amount of DNA as the cell that began meiosis.During which of the following steps does is genetic diversity produced? Mark all that apply. During prophase of mitosis During prophase I of meiosis During prophase II of meiosis During anaphase I of meiosis During fertilization
- How is the outcome of meiosis different from the outcome of mitosis? The daughter cells produced in mitosis are genetically different from the parent cells, but have the same number of chromosomes, while these are genetically similar in case of meiosis and have fewer chromosomes. The daughter cells produced in mitosis are genetically similar to the parent cells and have the same number of chromosomes, while these are genetically different in meiosis and have half the number of chromosomes. The daughter cells produced in both cases are genetically similar to the parent cells, but in meiosis, there are fewer chromosomes. The daughter cells produced in both cases are genetically different, but in mitosis, there are fewwer chromosomes in daughter cells.Which of the following is/are true of MEIOSIS but NOT MITOSIS?
