Gregor Mendel

Introduction

In this topic we will talk about Gregor Mendel’s work and discoveries and how does this discoveries affect the way we see genetics now days. Gregor Mendel was a monk that dedicatedpart of his time to study what we know call the laws of inheritance. Mendel started his work studying plants and how the cross of different species of plants results. Mendel initialize the scientificstudy about genetics that we now know as genetics, is the key to understanding what makes an organism unique.

Objectives

* To understand and make understand better the concept of heredity,genetics, dominant, etc.
* To explain the different experiments Gregor Mendel made to discover the laws he made and to get to the conclusions he did.
* To demonstrate how are genetics and heredityrelated and how do they were discovered.

Experiments Of Gregor Mendel

Mendel began his investigation into variation, heredity and evolution in plants. He chose to study in detail the commongarden pea, Pisum, which he grew in the monastery garden

The Pea Plant Experiment

During sexual reproduction, male and female reproductive cells join in a process known as fertilization to producea new cell. Pea flowers are self-pollinating, which means that sperm cells fertilize egg cells within the same flower, producing an identical offspring. To cross-pollinate pea plants, Mendel cut offthe male parts of one flower and the dusted the female part with pollen from another flower. He made that experiment to learn how some traits were determined in self-pollinating.

He came to threeimportant conclusions from these
Experimental results:

1. The inheritance of each trait is determined by "units" or "factors" that are passed on to descendants unchanged      (these units are nowcalled genes)
2. That an individual inherits one such unit from each parent for each trait.
3. That a trait may not show up in an individual but can still be passed on to the next generation.
