Question

During sexual reproduction, gametes, or sex cells, are produced through the process of meiosis.



How many chromosomes should be in the cells labeled with an X?

Answer 1

hey there

Answer 2

Hi. Sorry I just really don't understand Biology at all...

Answer 3

ah this was like beginning of the year for me i have honors biology

Answer 4

i completely forgot ;~; @kittiwitti1 can u help here?

Answer 5

@ILovePuppiesLol *gets yanked out of math*
*falls on floor*
w0t m8 im busy

Answer 6

danget

Answer 7

*helps u up*

Answer 8

help this person xD

Answer 9

>_> idk what this is though

Answer 11

read the entire thing but look under the meiosis and chromosomes :)

Answer 12

@Mizuki What do u think the answer is ?

Answer 13

@kayleebug29

Answer 14

not @Mizuki

Answer 15

um sorry lol @kayleebug29 what do u think the answer is ?

"During sexual reproduction, gametes, or sex cells, are produced through the process of meiosis.

Sex cells are special. They have a different amount of chromosomes because they only have one 23-set, unlike other cells that have two 23-sets (64)

Answer 17

LOL mizuki is probably like w0t xD

@Rushwr @kittiwitti1 Sorry the site froze. I have no idea I am really terrible at Biology and always zone out...

Answer 19

Eukaryotic DNA is compartmentalized into the nucleus within the cell. The long double-helical strands of DNA are wrapped tightly around proteins called histones to form a rod-like structure:the chromosome. For example, cells in the human body have 46 chromosomes in total (this includes two sex chromosomes; XX for women and XY for men).

However, human sperm and egg cells produced through meiosis only have 23 chromosomes.

“Meiosis is reductional,” said M. Andrew Hoyt, a professor of biology at Johns Hopkins University. Meiosis produces daughter cells that have half the number of chromosomes as the parent cell. Thus, when fertilization occurs, the chromosome number is restored. For example, when the human sperm and egg combine during fertilization, they produce a zygote, a cell with 46 chromosomes. Since sexually reproducing organisms receive a set of chromosomes from each parent, each chromosome has a corresponding pair, or homolog.

The daughter cells produced during meiosis are genetically diverse. Homologous chromosomes (that is, chromosome pairs from the mother and the father) exchange bits of DNA to create genetically unique, hybrid chromosomes destined for each daughter cell.

Answer 20

omg @ILovePuppiesLol wth xD

Answer 21

from what the information says, what do u think the answer may be?

Answer 22

okai here it is then !!!!
When u have 32 chromosomes from parent cells the next step is DNA replication where 32 becomes 64 okai ?

Answer 23

Can u guys not spam this post please ? :) @kittiwitti1 @ILovePuppiesLol

Answer 24

@Rushwr okay. btw I'm sorry it's taking so long to reply the site is being slow and glitching

Answer 25

and that 64 chromosomes divides in to 2 daughter cells each having 32 chromosomes. And each of the daughter cells with 32 chromosomes give rise to 2 daughter cells. Making it to have 4 daughter cells at the end. And the chromosomes are divided equally there. so each of the daughter cells will have 16 chromosomes

Answer 26

Check out the meiosis part in the diagram

Answer 27

I've been trying to answer the question (even though I'm in the middle of helping someone in math lol), but then she posted that super long thing.

So do I stay and help anymore? xD

Answer 28

I think it's better to concentrate on helping just one person at a time so that u won't get in to these sorta stuff :) @kittiwitti1

Answer 29

Okay @Rushwr, I'll just stay here so I don't get extra notifications (and learn e_e)
Thank you for that though ^-^

Answer 30

@Rushwr Okay so if it equals 16 then each one is four so the answer is four?

Answer 31

nop nop check this out

Answer 32

Ohhh okay I see what you were saying!

Answer 33

good :)

Answer 34

@Rushwr can you help me with another one?

Answer 35

yeah open up a new question maybe and also hit on the best response button to medal me :)
