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.
The first person known to have used probability and mathematics to predict offspring was Gregor Mendel. In the mid-1800s, Mendel studied the inheritance of seven characteristics in pea plants, in which each characteristic had only two forms, e.g., white or purple flowers, round or wrinkled seeds, and tall or short stems. Through these studies, he developed three laws of heredity; the law of segregation, the law of independent assortment, and the law of dominance. The chromosome theory of inheritance, developed in the early 1900s, explains the mechanism underlying the laws of Mendelian inheritance.
In genetical experiments the principle of probability is used to predict the results at !% and 5% probability levels. If a particular character appears in 95 plants out of 100, it is considered as a significant character to be inherited. For reaching more accuracy it may be tested at 1% level.
Whenever Mendel performed a cross with pea plants, he carefully categorized and counted the many offspring. Every time Mendel repeated a particular cross, obtained similar results. For example, whenever Mendel crossed two plants that were hybrid for stem height (Tt), about three fourths of the resulting plants were tall and about one fourth were short. Mendel realized that the principles of probability could be used to explain the results of genetic crosses.
The more samples you use, the closer your results will match probability.

Gregor Mendel
He is known as the father of genetics. He crossed pea plants to determine the patterns of inheritance for certain traits.
False
Certain plants and animals will prefer environments of different pH levels. The pH will determine what types of plants grow in an area and this will determine what types of animals eat there!
True breeding plants were homozygous for all the characters expressed, hence inheritance of characters was better understood with the help of these plants.
