Since most of the questions ask you to cross a cat that you found there is no answer key. Teachers, please feel free to use this activity in … Continue reading

I should have my entire planned activity for my bio students to share by next week, but in the meantime I thought I’d write about the agouti and tabby genes. The presence of a dominant agouti gene affects pigment distribution along … Continue reading

When someone sent me an article about why most of the human genetic traits we like to use in genetics lessons are inaccurate I was, shall we … Continue reading
