The work of gregor mendel biology

Johann Gregor Mendel Father of Genetics Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits. He recognized the mathematical patterns of inheritance from one generation to the next.

Mendel and Inheritance What is heredity? Heredity is when certain traits are passed from the parents to the children. Traits are characteristics such as eye color, height, and athletic ability.

Heredity is passed through genes in the DNA molecule.

In biology the study of heredity is called genetics. Gregor Mendel Scientist Gregor Mendel - is considered the father of the science of genetics. Through experimentation he found that certain traits were inherited following specific patterns.

Gregor studied inheritance by experimenting with peas in his garden. Peas work as an excellent test subject as they can self-pollinate, cross fertilize, and have several traits that only have two forms.

This enabled Mendel to easily control his experiments and reduced the possibility of the outcomes to something he could record and manage. First he produced a parent generation of true-breeding plants. He made these by self-fertilizing the plants until he knew they bred true to the seven traits.

For example, the purple flowering plants always produced seeds that made purple flowers. He called these plants the P generation for parent.

Next, he produced a second generation of plants F1 by breeding two different true-breeding P plants. He then produced a third generation of plants F2 by self-pollinating two F1 generation plants that had the same traits.

F1 Generation Mendel found that the F1 generation all produced the same trait. Even though the two parents had different traits, the offspring always had the same trait.

For example, if he bred a P plant with a purple flower with a P plant with a white flower, all of the offspring F1 plants would have purple flowers. This is because the purple flower is the dominate trait. These results can be shown in a diagram called a Punnett square. The dominate gene is shown with a capital letter and the recessive gene with a lower case letter.Mar 11,  · The Work of Gregor Mendel Brilynn Schrader.
