Re: How many genes are the same in all humanbeings?

Hi!

Yes. Almost all humans have all the same genes, but each of us has a 
very small number of genes that are spelled slightly differently from person to 
person. Note that this doesn't mean they are different genes, per se, just that 
they are slightly different in sequence. These tiny differences make up much 
less than 1 percent of each person's genetic material (DNA), yet the 
differences are enough to create people with different appearances and 
different health. The gene differences are usually inherited, so the more 
closely related two people are, the more similar their DNA is likely to be. The 
changes between us and our parents occur mainly due to genetic recombination. 
If one inherits his grand parent's characteristics, the phenomenon is called 
atavism.

Hope this helps!

Thank you.
