(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 women.The process of meiosis in men is known as ‘spermatogenesis, (sperm reproduction) ...
Why do some cells in onion root tips undergo mitosis? Mitosis and Meiosis: Mitosis and meiosis are two types of cell division that each is used for certain functions. Mitosis is the type of cell division that is used for repairing cells and replacing them when they are damaged. On the oth...
Why do sperm producing cells divide by mitosis? It is because meiosis produces the cells whichinclude half the Chromosomes count tothat of parent cell. It produces female egg cell and hence when the 2 combine during the fertilization process the new cell produced has suitable Chromosomes count. ...
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...
Sexual reproduction is ubiquitous in eukaryotes, but the mechanisms by which sex is determined are diverse and undergo rapid turnovers in short evolutionary timescales. Usually, an embryo’s sex is fated at the moment of fertilisation, but in rare instances it is the maternal genotype that determin...
An overview of FISH results of extraovarian cells and ovarian cells is presented in Figure 2. Oocytes of small follicles are arrested in the prophase of meiosis I and are tetraploid. At this developmental stage of folliculogenesis, the four copies of each chromosome are held closely together, ...
The sister chromatids at each end undergo a separation in a plane at right angles to the previous one to give haploid (n) cells. In total, a single germ cell gives 4 haploid gametes. My explanation is long-winded, but I hope it answers all the OP's questions and more. Finding ...
At this point, however, it is worth asking an even more general question: what is the functional difference between crossover recombination in meiosis and recombination repair in somatic cells? In somatic cells, the faithful repair of DNA damage is essential for the maintenance of genome integrity...
