The cell division occurs in two forms, namely mitosis, which occurs in somatic cells to increase the mass and size of an individual, while meiosis occurs in sex cells to form gametes.Answer and Explanation: Become a Study.com member to unlock this answer! Create your account View this ...
Meiosis occurs only in reproductive cells to produce the gametes eggs and sperm. Meiosis consists of two rounds of divisions, each with five phases - prophase, metaphase, anaphase, telophase, and cytokinesis. Answer and Explanation:1 Meiosis accomplish four haploid daughter cells from one diploid pa...
The life cycle starts when diploid sporophytes divide by meiosis giving rise to haploid spores with half the number of chromosomes. Through mitosis, spores develop into multicellular gametophytes, which then produce haploid gametes. Fertilization happens when two haploid gametes come together forming dip...
Mitosis results intwo identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division. What will be the chromosome number after mitosis Why? At the end of mitosis, the two daughter cells will b...
managing to incorporate into gametes at rates higher than 0.5. This alteration of the normal process of cell division (known as drive) allows a rapid increase in B chromosome frequency in natural populations. Drive mechanisms can operate before, during or after meiosis14, but how the alteration ...
In pigs, melatonin has also been added to IVM and/or IVC media to enhance embryo IVP, mostly using embryos obtained via parthenogenetic activation or somatic cell nuclear transfer (SCNT), with positive effects on IVP outcomes although the results are not completely consistent [20,21,22,23,24,...
meiosis, Reduction division; reduction of original number of chromosomes so that each sex cell (egg or sperm) has half the original number of chromosomes characteristic of the species.mesentery, Tissue that holds the intestine in place in the abdominal cavity....
In contrast, oocytes in the female arrested at the prophase of meiosis I remain hypomethylated throughout the fetal period [63,64,65]. DNA methylation will only be acquired by the same enzymatic machinery as that in male germ cells [66, 67] in the post-pubertal period during each cycle ...
When a primary germ cell gets ready to begin meiosis the DNA is first copied in the same way as it occurs for mitosis. This cell then undergoes two divisions so that each of the four final cells only has half of the original DNA....
Which stage of meiosis results in 2 cells with 46 chromosomes? Where in somatic cells does mitosis occur? Each chromosome has two: a) Chromatids. b) Centromeres. c) Centigrades. d) Chromatins. During meiosis II, does DNA replication occur again?
