Gregor Mendel

Founder of genetics

Background information and Early life

Gregor Mendel was born into a poor childhood but discovered the foundation of genetics that we know of today. Johann Greggor Mendel was born in Czechoslovakia (Present day Czech Republic) in 1822. To go to school, Gregor had to tutor other students to get money. After graduating, he couldn't find a job, so he returned to the family farm. Mendel was accepted to the University of Olomouc in 1841. Although he spoke a different language, he earned top marks in math and science.

Experiments and Data

Mendel wondered how many different forms would result from the random fertilization of two kinds of pea plants? So Mendel took one yellow pea pod and one green pea pod, in the first batch, all were yellow. He took two from the first batch and crossed them and ¼ of them were green. He figured out that Pods from the first batch carried a dominant (yellow) gene and recessive (green) gene. A dominant gene is a gene that will overpower another gene. A recessive gene that gets covered up by a dominant gene. So if a child pea pod carries at least one yellow gene, the color would be yellow, if it doesn't it would be green. Other dominant genes are round seed shape and long stem length. There were no co-dominant genes (a gene that is neither dominant nor recessive).

How Mendel impacted the field of genetics

When Mendel brought his data to the table, he found that, scientists didn’t react at all. Most scientists didn't fully understand his work. His work still remained untouched until the early 1900s came around. Independent scientists rediscovered and published his work. Some experimented what Mendel did long ago and got the same results. Later these results where referred as "Mendel's laws" and they became the foundation of genetics.
