Thanks to Kirby Zornes of LWSD for her fantastic original ideas on "Dropping your genes"

Part One

In this exploration each person and their partners must take a good long look at themselves, determine your correct traits and try to figure out how you got them. Most of the traits we will look at are either dominant or recessive.

We will be looking at 25 different traits. Your job is to work with your partner and observe which trait you show. Then enter the name of the trait in the Phenotype column of your worksheet.

Next put the appropriate letter symbol(s) in the Genotype column. If you show the recessive trait, you may automatically assume that you must be homozygous recessive and can record that for genotype. (for example gg - a square chin)

However, if you show a dominant trait, you must record both homozygous dominant and heterozygous (GG, and Gg) symbols. That’s because it is almost impossible to tell if your parents are heterozygous or homozygous dominant for any trait. To do so your parents would have to have at least twenty plus offspring, and I’m not sure they’d like that too much, just ask your Mom! (You might not either. Imagine washing the dishes for 22 every meal, or slinging a hammock with your 10 brothers or sisters!! )

(Disclaimer - 1. All right you budding geneticists! Some of these are not exactly Precisely correct, humans are way too complex to nail down so simply, but they are awful close and this whole thing is lotsa fun, so lets just do it!!!
