7.5.2 Genes and HeredityWhy do you look a little like your mom, and a little like your dad? How come some traits skip generations? Why can't Mr. Lee ever have a blue eyed baby? I know these questions keep you up at night, so learn about genes and heredity to figure it out!

Dominant and recessive alleles, genotypes and phenotypes, inherited vs. learned traits (nature vs. nurture), Punnett Squares, homozygous and heterozygous genotypes, there are lots of new terms you must know to fully understand genetics.

But the short of it all is, we inherit genes (on chromosomes) from each of our parents. That determines most of who we are!
