Meiosis

[Hooligan]

Hi Guys,

Just have a question about Meiosis, if Meiosis is the process whereby it allows organisms (like ourselves) to reproduce gametes, and we know that the resulting daughter cells from the process will contain half of the number of chromosomes of the parent cell, then what IS the parent cell? It can't be a gamete, otherwise it would be half of half of a normal parent cell.... So would the parent cell of meiosis (producing gametes) just be any cell in our bodies? *is slightly confused* Thanks for the help!

Do we learn this in Unit 1? (just wondering...)

[lexitu]

The parent cell is the cell coming from the gonads (sex organs). Not any cell, just cells in that area. Also note that gametes are produced, not reproduced.

And yes ATAR, unit one.

It's taught again in unit 4.

[iNerd]

didn't know you were doing bio atar???

Dropping out of Specialist.

[iNerd]

Wow. as if, specialist is awesome, are you just gonna do further next year?

Lol my spec average is higher than my methods average -,-

Correct - Further. Uh you don't have 'the Russian' do you?

[iNerd]

no i have Dr. G. Honestly the russian is a very good teacher its just he can lower your morale...
Answer my PM
Are you even gonna try in Bio 1/2 then?

...I'm not going to pass a Russian's vectors test. Atm I'm coping with surds

Oh and if I don't pass I won't get my diploma which would be the biggest waste of 30 credits -.-

Guys, seriously the Diploma is a waste of time. Everyone knows that. And 'the Russian' is awesome, his surds test was actually much easier than last years one.

Expanding on this, there are specialised cells that sit in the gonads to produce gametes (eg in the seminiferous tubules for men). It's certainly not any cell in your body randomly producing gametes for transport to the ovaries/testes

Thanks for the input guys. I didn't think it'd be any cell in the body either, was just throwing it out there it terms of the options.
So, from what you guys have told me: the gonads PRODUCE the gametes and they do not reproduce them and neither are the gametes reproduced. See, that makes complete sense to me, then why does it say in my lecture notes: "Meiosis enables organisms to reproduce gametes (sperm and eggs)..." Thats what confused me, 'cause if it were to reproduce, the parent cell would have to be the gamete itself, and it couldn't just continue to halve itself...! xD n00b lecturer? Judging by how she handled the lecturer, I'm thinking so. 1) she got the lecture notes from another lecturer, 2) during the whole lecture, all she did was read out what was on the slides... she hardly expanded on the points on the slide or displayed what she knew, in depth.

I'm in Uni btw guys.

Could just be poor phrasing and the lecturer means reproduce in the sense of produce repeatedly (ie reproduce the same thing over and over again). As you can see from this diagram, there is definitely a diploid cell that starts the process.

What course/uni?

Nice... what ya looking to get into later on? Med?

[Russ]

Most likely, yes
