Eye color punnet square disproves evolution?

You have misunderstood Mendellian genetics.

Mendel showed that mixing one trait always resulted in a 3:1 ratio between dominant and recessive phenotypes, his experiments with mixing two traits showed 9:3:3:1 ratios.

Not nearly as simplistic as your experiment.

Eye color is not dependent on a single gene, pumpkin, so trying to work it out on a Punnet square is not as clean as it would have been if, for example, your teacher used tall/short in pea plants, the same characteristics that Gregor Mendel, the father of the science of genetics, used in his research, or went with something a bit less inclined to blend.

Hemophilia, male patterned baldness, and other, similar sex-linked characteristics are clearer and easier to understand, although I understand your teacher's wish to involve you in the lab and make it seem personal.

You have not disproven evolution, though.

In fact, if your data were correct, all the children would have to be "bg". There would be no other possibility. However in reality, eye color is controlled by several different genes, not just one from each parent. In any case, this relates only to immediate genetic inheritance. It has nothing to do with biological evolution.

You do not know the genes of your parents. You are only guessing. Blue is recessive, but also the natural color - so if the trait does not manifest, the person may have blue eyes, but double dominant genes. Furthermore, you also don't know your parents are your biological parents.

Eye color is multi- factorial. High school teaches you Mendelian. Polygenetic traits do not produce Mendelian ratios. What you've been taught in Biology is only a summary.

...Assuming you actually thought a clueless teen caught something no expert in genetics had noticed.

Mother's gamete- Only 1 i.e. abcd Father's gametes- 16 That would be a 16x1 punnett square.

That doesn't "disprove" evolution...but it might suggest that you're adopted. Or that mom was fooling around...:)

Or that (and this is actually the case) eye color is actually more than a simple case of one "gene."

Peace.

Genetics are a lot more complex than the stuff they teach at school m'dear

Anyhow, what does this have to do with evolution?

Eye colour is a mix. Perhaps green is 'bg'.
