Sex cells (gametes) are examples of haploid cells. In humans (as well as other higher forms ofliving things), the somatic cell contains two copies of genes. As such, they are referred to as diploids. They produce haploid gametes throughgametogenesis, a process that makes use of meiosis tha...
Meiosis produces haploid gametes. At fertilization, male and female gametes fuse to restore diploidy in a zygote, which develops into a new life. At sex maturation, diploid cells enter into meiosis, culminating in the production of haploid gametes. Therefore, diploidy ensures pluripotency, cell ...
The two cells then enter meiosis II, at the end of which the sister chromatids separate and the cells divide, leaving four male and femalesex cellsorgameteswith half the number of chromosomes as the parent. Following meiosis,sexual reproductioncan occur. Gametes randomly join to form uniqueferti...
Is meiosis a part of the cell cycle? Mitosis produces which cell type? Haploid, diploid, chromosome, gamet? Is a heart cell a gamete or somatic? Does meiosis occur after fertilization? What are examples of haploid cells? How many autosomes are in a haploid human cell?
Meiosis comprises a pair of specialized nuclear divisions that producehaploidgerm cells. 减数分裂由两次产生单倍体生殖细胞的核分裂组成. 期刊摘选 Finally, in the sporic life cycle, the living organism alternates betweenhaploidand diploid states. ...
The diploid sporophyte undergoes meiosis to produce unicellular haploid spores. 2. The spores divide mitotically to produce the haploid multicellular gametophyte. 3. The gametophyte use mitosis to produce haploid gametes, either sperm or retained eggs. 4. Male sperm travel to the egg-bearing ...
of meiosis involves duplication and then separation of the chromosomes, followed by division into two daughter cells that each contain half the number of chromosomes as the original cell. In the second phase, each daughter cell divides to form an additional reproductive cell. See Note atmitosis. ...
Answer to: Mitosis results in __ cells and meiosis results in ___ cells. a. diploid, diploid b. haploid, haploid c. haploid, diploid d. diploid,...
They do not undergo mitosis with haploid cells; instead, they produce haploid gametes through meiosis. Hence, this option is wrong. 5. Analyzing Option 4: Muscle cell of human: - Muscle cells in humans are diploid (2n) and do not undergo mitosis as haploid cells. This option is also ...
