hey guys, I have a couple of quick meiosis questions



1. How many different arrangements of tetrads are possible during Metaphase I?

I know that the tetrads randomly align on the metaphase plate....so shouldn't the answer be 2 different ways? If each has the option of going to either end of the pole?


2. How many cells formed during meiosis are genetically identical (assume alternate forms of genes exist on homologous chromosomes)

Trick question right? none?

3. How many tetrad complexes are present in metaphase I?

2 right?


Directions told me to start with two pairs of homologous chromosomes.



Thanks,

NN

Okay if I'm interpreting your question correctly, the answers are:

1) Yes, the answer is two.

2) There should be two pairs of identical gametes formed. Remember during MII, the cells that are formed are identical to each other - assuming no crossing over.

3) Yeah, I think the answer's two.

So here's a quick-and-dirty picture of what I *think* you're describing

In the picture, there are two possible arrangements during MI - either the dominant genes end up together, or they end up apart. So there's two possible arrangements.

Let me know if this helps! :)
