Hi Billy,

Well, we didn't collect DNA exactly, but we did collect pin feathers that will be sent to lab where DNA will be extracted from cells in the shaft of the feathers.

We'll be studying DNA later this year, and you will find out that our DNA shares many similarities to other organisms' DNA, including birds. Because we are both animals, we share many of the same cellular processes and use many of the same enzymes (which are coded for by our DNA). Of course, we don't look like birds, so we have some differences, too!

As far as comparing individual geese....they do kind of all look the same, huh? Until you really get close enough to look at them. They are different from each other just like humans are different from each other. Different heights, weights, lengths of wings, legs, bills, etc. So, even though all snow geese share much of the same DNA, they are each different from the others as well!

The differences between 2 snow geese would not be as great as the differences between a snow goose and a human!

Great questions! I can't wait to get to Genetics!
