Next week, I'm teaching genetics and other reptile related subjects to every 7th grade student at a local school. We did this last year and when I talked about recessive, co-dominate and dominate genes, the kids were lost. They talked in terms of little "t" and big "T". However, they did understand me talking about heterozygous and homozygous morphs.

I'm a business major MBA, not a biologist and am a little surprised that the school keeps calling me back to teach something that was not my major. We spend two full days at the school and teach around eight 90 minute classes. I want to do a better job of making it relevant to the kids. Can anyone direct me to a genetics lesson that correlates big T little t to our BP morphs? I've been looking and don't see anything that I can use.

Thanks

Don
