A meiocyte in Prophase II of meiosis vii. One product of telophase II of meiosis

Crossovers occur between  a. non-sister chromatids during meiosis I  b. non-sister chromatids during meiosis II c. sister chromatids during meiosis I  d. sister chromatids during meiosis II

Why do eukaryotic cells need to go through the elaborate procedure of mitosis rather than simply dividing during interphase? Select as many answers as apply. 1.Daughter cells must be genetically identical to the mother cell, for homeostasis and ordered tissue growth.  2.Bivalent chromosomes must condense and be separated in an orderly fashion, to allow equal distribution of copies into daughter cells 3.Physically dividing the nucleus during interphase would likely lead to gross chromosome breakage and highly unequal assortment of genetic information into daughter cells. 4.Dividing the nucleus during interphase would have the same outcome as mitosis 5.Daughter cells must have half the number of chromosomes after mitosis than the mother cells 6.The homologous pairs of chromosomes need to be separated, to ensure copies go to the daughter cells.

Starting with one cell, how many cells will be present at the end of mitosis? Group of answer choices   A. 1 B. 0 C. 2 D. 6 E. 4

In mitosis one pare cell results in:  A. 2 Diploid Daughter Cells B. 2 Haploid Daughter Cells C. 4 Diploid Daughter Cells D. 4 Haploid Daughter Cells

A medical student is studying a liver biopsy taken from a regenerating liver following a partial hepatectomy. The student sees a dividing cell in which the chromosomes are aligned on a plate.
