The chromosomes as morphological units are visible only during cell division, that is, mitosis and meiosis. Because the appearance of the chromosomes might be different in different stages of division, a knowledge of what happens during mitosis and meiosis helps for an understanding of chromosome mor...
What are chromosomes made of? What is the difference between mitosis and meiosis? Which of them form gametes? Where does meiosis occur? Describe how the egg and sperm are produced or developed. How is genetic variation produced in meiosis? What is the name for the structure that is formed ...
During amphimixis: a) Meiosis occurs. b) The ovum finishes meiosis II. b) Sperm becomes capacitated. d) Gametes are formed. e) The male and female pronuclei fuse. During the development of mature sperm, what occurs during meiosis II? a. Spermatogonia replicate their DNA and divide to for...
MeiosisMicrotubuleMitosisSea starSea urchinThe early embryos of sea urchins and other echinoderms have served as experimental models for the study of cell division since the nineteenth century. Their rapid development, optical clarity, and ease of manipulation continue to offer advantages for studying ...
Gametes or gametic cells are sperm cells in men and egg cells, or ovum, in women. The sperm is the smallest cell in the human body. The ovum is the largest cell found in the human body. Answer and Explanation: Learn more about this topic: ...
Detailed studies on the exact mechanism of N2O mediated chromosome doubling during meiosis are also limited, but it has been suggested that N2O disrupts the spindle mechanism in both mitosis (Dvorak et al., 1973; Kato & Birchler, 2006; Kihari & Tsunewaki, 1960; Östergren, 1954) and ...
Heterosis boosts crop yield; however, harnessing additional progressive heterosis in polyploids is challenging for breeders. We bioengineered a ‘mitosis instead of meiosis’ (MiMe) system that generates unreduced, clonal gametes in three hybrid tomato g

(r2= 0.56), and most sporads of this form appeared to have four larger nuclei and one or two small nuclei. These extra nuclei are probably formed by laggard chromosomes at meiosis (Figure2e, also suggested by d'Erfurth et al. (2008) [27]), which form micronuclei visible at the spor...
