What We Did Today...
- Punnett Squares
- Finished the simple worksheet
- Dihybrid Crosses
Thoughts About The Material...
I think the punnett squares are weird and kind of confusing, just doing the dihybrid crosses for simple genes. That got me wondering how complex a punnett square would be for trying to figure out the phynotype or genotype of a human, because we have so many complex traits, unlike the pea plants that had green or yellow seeds, human have many different characteristics.
Above and Beyond...
I followed this link http://faculty.clintoncc.suny.edu/faculty/Michael.Gregory/files/Bio%20101/Bio%20101%20Lectures/genetics-%20genes/Image1.gif
and didn't quite find an answer to my question but I did find a picture of what a trihybrid cross would look like, and it seems pretty complicated so it gives you an idea of just how complicated a human punnett square would be.
(I tried posting the picture but my computer wouldn't let me, sorry)

ya - 64 possibilities makes it a bit cumbersome, and that's only 3 traits. Now you "get" why we stop at dihybrid.
ReplyDeleteOften, a search to answer one question can still uncover other interesting info. Well done.
