We found that, on average, there were 18 chromosomes per cell in anaphase.
But they ask us, if we didn't have a microscope, how we could predict the number of chromosomes we were going to find...


Personally that sounds like a really stupid question. We DO have microscopes, no reason not to use them. without them we wouldnt even know what a chromasome was...
That'll do donkey, That'll do.

I know, lots of things are wrong with this class. But I complained enough (politely), and I don't want them to hate me :?
I'm a good student, and it's not my habit to go on discussion boards to get answers to my homework, but here, without any lecture or pointers or helpful lab notebook, I have no choice really...

Thank you so much for your help, all of you! Druid, I will try your answer! I will be sure to come back and tell you what the expected answer is.

Thanks!

I guess this was the correct answer, since I got an A =)

THANK YOU!

I discovered that, for a zygote to be formed, a haploid number of chromosomes should come from each parent for the diploid number to be restored in the zygote.Also, mitosis undergoes four main stages; pro phase, meta phase, ana phase and telophase

the number of chromosomes in a human is 46. hence, 2n=46 where n is haploid number.
