Explanation / Answer

Mitosis produces exactly identical cells. Mitosis is called as equational division. Body cells of our body undergo mitosis to give rise to identical cells. Primary oocytes undergoes meiosis to give (d) one ovum (secondary oocyte) and one polar body. The first stage of mitosis, when the chromosomes condense, nuclear membrane breaks down, and spindle forms, is Prophase. Diploid cells (e) all of above are correct. Homologous chromosomes exchange genetic information by (e) crossing over The cell produced by the fusion of an egg and a sperm is the (c) zygote The two copies of each chromosome in body cells are called (b) homologous chromosomes. The phase of the cell cycle during which the cytoplasm divides to form two cells is (d) cytokinesis Sexual reproduction increases genetic variability through (e) a, b, c At the end of telophase II of meiosis, each of the four resulting cells contains (c) haploid set of chromosomes, each a single chromatid In mitosis, the chromosomes line up at the equator of the spindle during (c) metaphase Zygote has (e) homologous pairs of chromosomes
