need HELP!!! plz?

Question

hey .... i am an 9th grader i and wy have this realy hard question and i've reasercherd but i cant seem to find it ...

THE QUESTION IS: do u agree or disagree that homologouse chromosomes are found in gametes.Explain.


(plz help... i realy appreciate it if u do!!)

Answer 1

Homologous chromosomes are chromosomes that code for the same genes, only one comes from your father, and one from your mother. For each regular human cell, homologous chromosomes come in pairs. That means that in your cells, there are two genes coding for each thing in your body.

I wish I could draw you a picture.

Anyways, gametes are sex cells. Therefore, they only have one of each pair of chromosomes because the cell will combine with a gamete of the other gender to have the normal number.

Maybe this will help: each non-sex human cell has 46 chromosomes. This means it has 23 homologous pairs. Get it?
But the sex cells have to have half that because the number will be doubled when it is fertilized. So a gamete, a sex cell, does not have homologous chromosomes because they are only called homologous when they are a pair.

So, the short answer to your question is, no.

If you didn't understand me, maybe this will help:

Answer 2

Gametes are haploid chromatids. You disagree, because meiosis takes homologous chromosomes, which are diploid and separates them into haploid gametes.
