Gregor Johann Mendel is often called as Father of modern Genetics.Before him,many scientists roughly used to study about inheritance.But Mendel strictly considered all the phenotypic and genotypic characters about the plants.For example when he was studying on pea plant(Pisum sativum),he considered all the external characters such as shape,colour..etc.Hence he was more particular than earlier scientists.
mendel Science Major: Gregor Mendel was the father of genetics. Here is a short biography from thinkquest.org. Gregor Mendel who is often called the "Father of Genetics" was born on July 22, 1822 to a relatively poor peasant family. As an adult he entered the Augustinian monastery in Brunn, which at that time was known for being one of the best centers of learning in the scientific field. He went to study science and mathematics at the Univeristy of Vienna but failed his tests to receive a teaching degree. He later returned to the monastery where he became an abbot and spent the rest of his life. At the monastery, he started investigations of variation, heredity and evolution of plants at the monastery's experimental garden. Because he knew other scientists had done experimental crossings between peas, he already knew that he could observe the traits of the different pea generations. Mendel was fortunate to have all the needed materials at the monastery. There were a large amount of true-breed peas plants available to him. Mendel raised and tested over 28,000 pea plants between the years 1856 and 1863, carefully analyzing seven pairs of seed and plant characteristics. He specificly studied plant height, pod shape, pod color, flower position, seed color, seed shape and flower color. He made two very important generalizations from his pea experiments, know today as the Laws of Heredity. Mendel coined the present day terms in genetics: recessiveness and dominance. In 1866 he published his work but it didn't take affect in the science field until 1900, years after his death. As the theory of evolution spread so did his findings and laws. Many other biologists used Mendel's research as a basis for their own and Mendelian genetics is studied and taught throughout the world. Gregor Mendel died in Brunn on January 6, 1884.
Each trait is controlled entirely by a single gene on the chromosome. Thus their phenotype is determined only by the combination of the two genes for that trait inherited on the pair of chromosomes received one from each parent, the genotype. Many other traits are controlled in much more complex ways involving multiple interacting genes, possibly even on different chromosomes. This can make them very difficult to predict or even nearly impossible to predict in some cases. To a large degree Mendel was very lucky to have picked those specific traits to study!
the reason they are so reliable is because he used peas as his plant of interest. an peas have only 2 different things they can be. short or tall. so it was easy to conclude all of the different outcomes of the offspring of the pea plants because of the of his drawn punnett square. which shows that if a tall dominant pea plant goes with a short it will be tall. and if it goes with a tall it will be tall. but if short goes with short then it will be short. so only 25% vof the time a pea plant will be short
Desert biomes can have both large and small plants. Large plants in deserts, like cacti and Joshua trees, are adapted to store water and survive in arid conditions. Small plants, such as shrubs and grasses, have shallow roots to quickly absorb water after rare rainfall events. Both types of plants have evolved various adaptations to thrive in desert environments.

Mendel studied a large sample of pea plants to ensure the reliability and statistical significance of his results. By observing numerous plants, he could identify consistent patterns of inheritance and reduce the impact of random variations. This large sample size allowed him to formulate his laws of inheritance, such as the Law of Segregation and the Law of Independent Assortment, with greater confidence in their applicability to future generations. Ultimately, it helped establish the foundational principles of genetics.
The more samples you use, the closer your results will match probability.
Mendel studied a large sample of pea plants to ensure that his results were statistically significant and reliable. By observing a wide variety of traits across many plants, he could accurately identify patterns of inheritance and establish fundamental laws, such as the Law of Segregation and the Law of Independent Assortment. A larger sample size also helped to minimize the effects of chance variations and provided a clearer understanding of genetic ratios. This rigorous approach laid the groundwork for modern genetics.
it gives him a more accurate description of the living plant.
Counting large numbers of plants was important for Mendel because it allowed him to observe patterns and ratios in the inheritance of traits. By analyzing a large sample size, he was able to establish the fundamental principles of genetics, such as the segregation and independent assortment of alleles. This laid the foundation for our understanding of heredity and paved the way for future research in the field.
He worked with large numbers of plants
it made his actual results approach the results predicted by probability.
they can be grown easily and in large number their reproduction can be manipulated
