Genetics with a Smile

Today Mr. Houde took the reins and helped students with lots of new genetics terms. We learned about dominant and recessive alleles, the difference between genotypes and phenotypes, as well as homozygous and heterozygous allele combinations. Students used their new knowledge to do an activity called "Genetics with a smile." In this activity students flip a coin to determine which allele their "kid" inherits from the given heterozygous parents. After students determined the kid's genotype they described the kid's phenotype, and then drew a picture of their kid, including all of the traits determined by coin flipping.​ A downloadable worksheet version of this activity is listed at the bottom of this post. 

Gold Tape Question: In class Mr. Houde explained that identical twins are also known as monozygotic twins, which means they come from a single egg that splits into two separate cells that begin to divide into two separate people. The word monozygotic comes from two Greek Words, mono meaning one, and zygote. What is a zygote and how does it relate to identical twins?
