one curly, one wild 2

one curly, one wild

2 curly, 2 wild 1:1 ratio

mated male curly with female straight= 2 straight 2 curly

mated curly with curly= 2 straight and 2 curly

2 curlys again = 1 wild, 1 wild, 2c, 2c (ratios)

THIS VIOLATES THE RULES!

why?

Well, we then explored the characteristic of true breeding and mated a male curly with a female curly. And found that there was a 2 (curly) : 1 (wild) ratio. Therefore, we hypothesized that culry wings are a recessive trait, and even more, if the genes start off as homozigous, then there will not be a 3:1 ratio. This is also true for starting with wild wings, because if you mate two wild winged flies, you will also NOT get a 3:1 ratio.

We then tried some other combinations, but many of these had 3:1 ratios.
