I also find that the females in my family are more probable to inherit brown eyes as compared to males. The same is observed with black eyes. Evaluation: think that my experiment went very well. The graphs and processing of the data is accurate. However, the limitations of this experiment were that I was not able to obtain the data of fathers parents and my mother’s father because they were deceased. Also, I could have included myself in the data to have a wider database.
