How the Body Works : Gamete Cells

Gamete Cells

Gamete cells are produced to transmit genetic information from parents to their progeny. The cells are formed by a special process of cell division, called meiosis, which results in the halving of the chromosome number in each parental gamete so that the full complement can be restored when sperm and ovum unite. First , the chromosomes appear in the nucleus of the cell and then duplicate. Like chromosomes link together and exchange different section of their length before separating and lining up across the center. They are pulled to opposite poles and eventually two cells are formed, each one containing one member of each pair of chromosomes from the original cell. Then a second division begins and, in the same way, the chromosomes arrange themselves across the center of the nucleus. This time one-half of each chromosome, a chromatid, moves to the poles of the nucleus. Within the four cells that are formed each chromatid will eventually replicate to form a chromosome and each gamete cell will contain half the original chromosome number.

That voice reminds me of the H.a.l. 9000 from 2001 a space odyssey. lol I love it!

@JEAK47 From one parent. If you're a man, in your testacles normal body cells undergo meisos to become sperm cells. The normal body cells contain chromosomes from your father and from your mother (they are diploid) but during meisos this genetic material divides into 4 sperm cells which means 2 of them have your father's chromosomes and the other two your mother's. But of course, because of homologous recombination neither of the 4 sperm cells isn't completely your father's or your mother's.

@biba56  does a gamete contain chromosomes from one parent or both

[baabaa33]

@Romaniangirl10 yes they should

@bmace15 a gamete cell is a sex cell. In humans, it is either a sperm cell or an egg cell. So imagine that the four rightmost cells in the screen are sperm cells and then imagine that each time you masturbate, a huge amount of these had to have been produced and for each, a meiosis had to have had occured.

what the fucking fuck, cant someone explain it in normal english like this happens then this then this, like not blah blah bioligy terms!!!!

[bmace15]

im confused this didnt explain what a gamete cell is?????

[deviantcreep]

ahahahah!

[Tylakk]

I was about to say the same thing!

"And that's where babies come from... Dave."

[Romaniangirl10]

Shouldn't the four ending gametes all be unique?
