Another question about meiosis!!?

Question

can someone explain what happens in all the phases...in like smaller words...lol...plz make it simple...i dnt get the online stuff and the stuff in my book cuz i dnt understand half the words they use!! plz i knw there is alot of steps...(or i think there is) but i would greatly appreciate it!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

There IS a meiosis tutorial if you'd just take the time to Google meiosis instead of continually asking about in here! It looked pretty easy and understandable. I know, textbooks can really suck!!! Try the Google search, I think it'll help! Good luck.

Answer 2

Meiosis I is incredibly only like mitosis, in meiosis II the two daughter cells divide back to offer 4 haploid cells. In asexual reproduction, a single guy or woman is the only discern and passes copies of all its genes to its offspring. The genomes of the offspring are only approximately suited copies of the discern's genomes (i.e. there is not any genetic version as a guy or woman that reproduces asexually supplies upward push to a clone). In sexual reproduction, the behaviour of chromosomes for the time of meiosis and fertilization is responsible for lots of the version that arises each era (crossing over in prophase of meiosis I, autonomous sequence at metaphase of meiosis I, random fertilization). because of the fact the atmosphere ameliorations, the inhabitants might proceed to exist if, in each era, a minimum of a few of its members can cope effectively with the hot situations. distinctive genetic ameliorations might artwork greater beneficial than people who interior the previous prevailed. Sexual reproduction (meiosis) contributes to genetic version latest in a inhabitants. desire I helped =)

Answer 3

alright lets see if i can help

meiosis is when reproductive cells (sex cells) duplicate

so the phases are prophase metaphase anaphase and telophase (there is a 1 and 2 of each of these, and i remember the order by PMAT)

prophase 1- the chromosomes (strings of DNA) start to clump together and become visible. the nuclear envelope (the membrane around the nucleous of the cell) dissolves.

metaphase 1- the chromosome line up in the equator of the cell, they look like and X . each side of the X (as in the right side or left side) are sister chromatids, and are exactly the same.

anaphase 1- the chromosomes seperate at the centromere (the very center of the X where the sister chromatids are held together) and they go to opposite sides of the cell, kinda like this...

meta-( X ) ................. ana- (> <)

the ( ) are the cells, the X is the chromosome and the >< are the seperated chromatids


last is telophase 1- this is where the chromatids start to dissapear and the cytoplasm (all the junk inside the cell) is seperated and a cell wall begins to form, like this

(> | <) ....... ( > )( < )............(>) (<)



now the PMAT 2 stages are basically the same thing, so you end up with four "daughter" cells.
