DNA is the underlying code for human life. Variations in this code result in the physical diversity observed between humans. While some physical traits are determined by just a few variations, many more are governed by several to hundreds of genes. Also, while we might point to one ancestor as the source of a particular trait, in fact many of our traits are determined by contributions from both our maternal and paternal ancestors. The interactions of these gene alleles and their products result in our unique physical characteristics. With chromosome mapping, we can also trace the origins of some of these traits and characteristics.

WOW!! Excellent webinar full of VERY interesting information and well presented! Thanks so much!!
LOTS of good comments and information and a syllabus to help us through it. Complicated topic though!
Information clearly presented. Looking forward to the syllabus.
For someone who did not do well in the hard sciences in school, I could follow and understand today's talk.
Very interesting and informative.
Interesting information about genetic expression. I understood a lot of it, but still need more education on this subject. Paul was an excellent presenter, and he didn't take it for granted that we would understand or have prior knowledge of the subject. Nor did he talk down to us. I enjoyed his presentation. He was very informed about genetics and able to answer questions from the audience. Thanks, Paul, for a wonderful explanation of our genes.
It's a beginning.
Great presentation.
