Does this mean that meiosis?
Meiosis is the process by which the nucleus divides in all sexually reproducing organisms during the production of spores or gametes.
Does this mean that music is never occur in organism that are haploid?
Organisms that are haploid, e.g. algae such as Volvox, Spirogyra, etc. show meiosis in the zygote. The haploid gametes fuse to produce a diploid zygote, which undergoes meiosis to produce haploid spores, which divide mitotically to produce gametophyte. A zygote is the only diploid stage in these haploid organisms.
Which cells can never undergo meiosis?
In multicellular plants and animals, however, meiosis is restricted to the germ cells, where it is key to sexual reproduction. Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).
What happens in meiosis I?
In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in meiosis that generates genetic diversity. DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis.
Which best explains the process of meiosis?
one full set of chromosomes, each with 1 molecule of DNA. Which best explains the process of meiosis? The cells that result from meiosis 1 are haploid, and each chromosome consists of 2 chromatids. … One of a pair of chromosomes with similar genetic information and from different sources like the sperm and egg.
Does meiosis occur only in haploid organisms?
Meiosis occurs in a diploid organism, not haploid. … An egg and a sperm are examples of those haploid cells.
Does meiosis only occur in diploid cells?
Most of the cells in your body are diploid, germ line diploid cells will undergo meiosis to produce gametes, with fertilization closely following meiosis. … The sporophyte phase is “diploid”, and is that part of the life cycle in which meiosis occurs.
Do meiosis occur in haploid cells?
Answer: Meiosis can take place only in a diploid stage (post-zygotic stage) because the zygote is the only diploid cell in the life cycle of such organisms. This meiosis an case of haploid organisms will occur of the fertilization.
Does meiosis occur in?
Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).
What is the difference between mitosis and meiosis?
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two 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.
