Genetics means a study of heredity. Johann Gregor Mendel’s contribution plays a significant role in genetic science. Mendel’s findings left a great trademark in the field of genetics and hybridisation. He is known as the father of genetics because his theory of inheritance in pea plants contributed to a good boom.
His study is divided into two papers. The first paper states the nature of the plants, which includes every part of the plant, such as the stem, seeds, leaf, and flower. Mendel chose a simple biological method with quantitative analyses and understandable to common people. In the year 1900, Hugo de Varis and Carl Corrins rediscovered Mendel’s findings.
Mendel’s Findings
Gregor Mendel’s findings led to a new invention in 1865. We inherit traits like eye colour, hair colour, speaking ability, height, etc., from our parents and grandparents. Gregor Mendel’s findings show that this inheritance is due to genes passed from generation to generation. His study on biological inheritance says that studying the heredity of life is a very important part of every living being, including plants, animals, and human beings.
Mendel’s Investigation contributed more to the field of biology. Mendel’s seven-pair experiments include coat cover, the colour of storage material, contrasting characters, affecting the seeds, characters in plants like distribution of flowers, shape, and colour of the pods, and length of the stem.
Mendel’s Findings are the most renowned method of explanation of plant hybridisation. He discovered that hybridisation also takes place in plants with the help of green peas. Gregor Mendel’s Finding explains the colour nature of the storage material. He explained it as seven different pairs. Mendel’s findings say that our inheritance is passed to us from our parents. In the same way, plants also get the inheritance from their parent plants. Gregor Mendel spent eight years on experiments on cross-breeding pea plants. As said earlier, he experimented on flower colour, flower position, plant height, seed height, seed colour, seed shape, pod colour, pod shape, etc., in different ways.
Gregor Mendel’s experiments
Gregor Mendel’s experiments are based on Mendelin’s inheritance which explains the theory of the pea plant, which states that when long and short pea pods are combined form new genes of the flower, which is blue and white. The pea pod is formed by pollination and is of average height and size of the parent pods. Mendel’s experiments explain to you the theory of human genetic growth through a simple vegetable small pea plant which leads to describing the genes, chromosomes and the functioning of cells that take place in all living beings.
Mendel’s experiments and the law of probability
Johan Gregor Mandel was an expert learner, priest, and scientist who made a mesmerising contribution in the field of genetics, which we came to know the origin of living beings and the changes which we face after a certain age is due to the availability of genes and cell in our body, these genes grow after some time, and we reach the maturity.
In 1856, he began decade-long research involving inheritance patterns in honeybees and plants. He set the experiment on pea pods because it is of average size, not much big or very small. Peapod is the primary model system and can be brushed easily by artificial pollen seeds.
In 1865, Mendel experimented on 30000 pea pods and successfully introduced the concept of genetic hybridisation to the public, but they were not accepted. Hence he demonstrated the concept and published the book called Experiments in Plant Hybridization.
Mendel’s work went unnoticed in the beginning. Still, years after, when new inventions took place, Mendel’s findings were rediscovered by other scientists. They named the theory as the blending theory of inheritance as continuous variation is caused by the action and reaction of parental changes that occurred during the intimation.
Steps and procedure of Mendel’s experiments:
To explain the theory, we have to know the certain steps involved in the experiment. Mendel conducted experiments following three different steps. The method used by them is as follows.
Step I: Selection of parents and obtaining pure lines:
Pure lines mean selecting the male and female pods with pure breeding capacity so that they produce offspring naturally with healthy and active pods.
Step II: Artificial cross of the selected parents to raise FI generation:
Mendel first selected the flower of the plant as a female plant, and the pollen of the male plant dusted on the stigma of the flower and the new pod was formed. He tried the experiment on many plants, and this process is known as the F1 generation.
Step III: Selfing of F1 hybrid to raise F2 generation:
He collected the different hybrids and divided them into two F1 and F2 generations. All are divided according to the size and breeding capacity.
Conclusion
Hence, Mendel’s findings cause a breakthrough in the biological field and reproduction system in plants. Mendel’s findings state that fertilisation plays a vital role, and the genes and cells are the parts that help us to grow and hybridise the new pods.
Mendel’s experiments explain to you the theory of human genetic growth through a simple vegetable small pea plant, which leads to describing the genes, chromosomes, and functioning of cells in all living beings.
