Day 50

Day 50!! This year is flyin' by! Only 130 more to go!
The AP Biology students reviewed (at least I hope it was a review) sex-linkage. Sex-linked traits are traits that are attached or found on the X chromosome.  Traits like color-blindness, hemophilia and Duchenne muscular dystrophy are all sex-linked disorders and, as such, are found most often in males.
The Biology students learned how pedigrees worked to track genetic traits within a family.  The students have an assignment:  put together their own pedigree and ask as many people as possible on that pedigree the following question - do you have hair on the mid-digit of your fingers? Hopefully, the people the students ask won't hang up on them.
The Chemistry students made gold (brass) pennies for the last (maybe) time today.
