Genetics

The study of genetics and heredity has been a part of science curriculum for quite a while now. Biology teachers can use the experiments and discoveries of Gregor Mendel along with Darwin’s explanation of natural selection to teach students the inner workings of genetics and heredity. Although I find the subject fascinating, students may tire of doing endless homozygous and heterozygous crosses on worksheets. Some of these worksheets and “boring” lessons can be replaced by some of the unique activities featured in Joann’s Picks and on our Facebook and Twitter pages this week.

One of the favorite pastimes of my parents and in-laws is to scrutinize my children and remark how each child resembles their respective sides of the family. My parents feel strongly that their grandchildren take after “our side” of the family in looks and temperament, while my in-laws feel equally firm that the children are much more like my husband and “their side”. I’m sure this same scenario is played out ad naseum in families worldwide; one wonders what happens in families with less-than attractive children.
