Usually all at one time.
Three.
1 time only which is done during the only interphase in meiosis.
DNA replication occurs once during mitosis. Replication also occurs once during meiosis even though there are 2 divisions that happen.
I think into two in mitosis and into four in meiosis. Hope this helps.
I've been studying meiosis and mitosis a lot in class, and if theres one thing I've learned from all this jibber jabber, it's that meiosis occurs in sexual reproduction, and mitoses ioccurs in asexual reproduction. Another difference would be the fact that during meiosis, the cell divides 2 times and ends up as 4 new cells.... During mitosis, the cell will only divide once and it will end up in 2 new cells
Chromosones are divided two times. Once during meiosis I and once during meiosis II.
in meiosis, or after the cell has split two times
Three.
2,4,6...
2
1 time only which is done during the only interphase in meiosis.
they double 30 times its wight
Remember that meiosis occurs during the production and maturation of gametes so it occurs very often! In males, it occurs virtually throughout their whole life and in females, meiosis I completes at every ovulatory cycle until menopause and meiosis II completes with fertilization.
In both mitosis and meiosis DNA replication only occurs once, during Interphase and Interphase 1, for mitosis and meiosis, respectively.
They replicate before meiosis begins, as it is the division phase. The chromosomes duplicate during interphase which is right before the beginning of meiosis. After going through meiosis I the chromosomes DO NOT duplicate nor do they cross over they simply continue on. Hope this helps. :)
the products of meiosis i. e. sperms, in men are several times more than the ova, in women
A cell undergoing meiotic division will divide twice, yielding 4 haploid cells.
