What is the difference between meiosis 1 and meiosis 2? a. What is the process of sexual reproduction? b. Why do we say that meiosis is essential for sexual reproduction? c. When do cells regain the normal chromosome number of body (somatic) cells? d. How does the alternation of meiosis...
Does mitosis produce somatic cells or gametes? Does mitosis occur in germ cells? Both mitosis and meiosis are preceded by How do you know if nondisjunction occurs in meiosis 1 or 2? Is embryonic development caused by mitosis or meiosis?
At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes. Does mitosis occur in ...
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...
Question: Where does fertilization of an egg cell usually occur? Ovulation & Fallopian Tube: The mammalian female provides her half of her progeny's embryo's genetic material through what is called an egg (also called an ovum). On a cycle, the female will ovulate and her egg will travel ...
Although BRCA2 has been mostly studied in the context of HR in somatic cells, it arguably has a more prominent role in meiotic HR, as across a broad range of species, fertility defects are the most common consequence of BRCA2 loss3,4,5,6,7,8,9,10,11. In meiosis, HR functions to ...
The primary gonial cell undergoes several rounds of mitosis, aborted meiosis I and normal meiosis II. The haploid spermatids then elongate with the growth of the sperm tails. The germ cells are shown in white, somatic cells are shown in gray. (b) Wolbachia (green/yellow) within a whole ...
What does the "Bt" inBtmaize refer to? A A gene that makes the husk of the corn too tough for insects to penetrate B A gene that causes the plants to emit a substance that is toxic to weeds C A gene that reduces the amount of water the plants need to grow ...
Does a zygote produce somatic cells by mitosis? What do chromosomes do in meiosis but not in mitosis? How does meiosis get its diploid cell? When mitosis is complete, and cytokinesis has taken place, do the two new cells resemble a cell that is just beginning interphase or one that has ...
Mitosis is a kind of cell division which occurs in all somatic cells and produces two daughter cells. These daughter cells are identical. The body uses mitosis to heal or repair from injury. It also uses mitosis to grow.Answer and Explanation: ...
