If you have the same answer as that then ingore this but if you don't have that question this is the one I had.

In pea plants the flower color may be either purple or white. Only one purple gene is needed for that color to show, while two copies of the white are needed to show. Which statement uses the correct terminology to define flower color in pea plants?
The flower color trait in pea plants is defined by two alleles: purple is dominant and white is recessive.
Q: A statistician collects the following height data in inches for a school district. The statistician says that it is a normal distribution. How did they draw this conclusion?
A: When graphed, the data creates a bell curve.
