George Johonn Mendel, was a great scientist who lived from 1822 to 1884. At an early age he began experimenting with plants by growing different varieties of garden peas.

The punnet square helps to determine what is likely to the outcome of specific genotypes combined together. (i.e. mom and dads) This diagram produces all the possible results of a union and makes it easy to give the probability of a certain characteristic.
