I would like to thank J_9 for her useful information on Artificial insemination cause I looked every where but couldn`t find a simple definition along with a few advantages and disadvantages of the procedure.

I would lkie to know the difference between monohybrid and dihybrid crossing in genetics and what does a gene actually looks like (with labelled diagrams) and how are genes with specific allels separated during meiosis.

Thank you

This is tough to show over a computer. If you go to any college campus library you can get access to a basic biology text, genetic section. Also perhaps at the public library.

Its a lot easier to see with the pictures.

Wikepedias page for both are okay... not great visually, but a start...

Thank you very much for the complement catting.

Ohh, now we are getting interesting!! The info you are asking for now has me a little perplexed though.

I am wondering though if you are talking about the punnet square or are you asking about a more specific trait or disease such as Wilms' Tumor, Chagas Disease or maybe Chron's.

Just a guess.

Great sites KP, however, I tend to steer away from Wikipedia because I am unsure of their accuracy (I really don't know). I got these ideas from doing a search on Medscape.

At a glance the info looked OK... and I agree, you need to be careful. A well written basic biology book with nice pics is really the best thing for the novice.

It truly is. While I could not find any pics on medscape, you had the best ones I could find. We just need to find the reason for the question now.
