When human somatic cells undergo mitosis are diploid cells made? Why do your chromosomes come in pairs? How are mitosis and meiosis similar and different? Explain the fate of cells produce by mitosis and meiosis. What is the difference between somatic cells and gametes? How does synapsis o...
Meiosis on the other hand is much more complicated than Mitosis. Thehumanreproductive organs (human sex organs) undergo Meiosis in cell reproduction. Mitosis creates 2 cells from a parent cell. But cell reproduction in Meiosis differs frommenand women. Meiosis forms4 gametes in men and 1 in wo...
Mitosis and meiosis are important processes. \\ a) What does each accomplish; \\ b) where in the human body can each occur and \\ c) how do the cells produced compare in chromosome number to the parent cells? What is the purpose or purposes of meiosis? Fully explain why is it s...
During fertilization the sperm and egg unite to form a single cell called the zygote which contains chromosomes from both the sperm and egg. Thezygote undergoes mitosis to begin development of the human embryowhich eventually becomes a baby. Do eggs and sperm arise by mitosis or meiosis? Mitosi...
These four daughter cells only have half the number of chromosomes? of the parent cell – they are haploid. Meiosis produces our sex cells or gametes? (eggs in females and sperm in males). Do humans have 72 chromosomes? Chromosomes the building blocks of you: Within the human body, there...
Depending on population structure, the ratio of male to female gametes may be male-biased in Plasmodium, but because gametogenesis involves only three more rounds of mitosis for each male compared with each female, the opportunity for mu- tational bias to result in fast-male evolution...
Their generative cell contains a few plastids which, however, are selectively degraded (by an unknown mechanism) prior to division of the generative cell into the two sperm cells in pollen mitosis II. Both mechanisms must be under genetic control of the paternal gamete. Species of...
They are not located closely together at any time, even during "usual" cell division, which is mitosis. They only come together in special cells in the gonads (testes or ovaries) when undergoing the special process of meiosis. In diploid cells, of the 23 pairs, 22 pairs are perfect ...
In many eukaryotic cells, the cell cycle proceeds as a sequence of contingent events. A new cell must first grow to a sufficient size before it can begin DNA replication. Then, the cell must complete DNA replication before it can begin mitosis. Finally, the cell must successfully organize a...
