What explanation did Mendel offer for the results of his experiments?

At the time of Mendel, biological science did not yet have information about the mechanisms of cell division and the role of chromosomes in heredity. Mendel’s scientific insight allowed him to get ahead of his time: to explain the results of experiments on inheritance, he proposed the hypothesis of gamete purity. The discovery of mitosis and meiosis confirmed the validity of this hypothesis, which has become a theory. Mendel suggested that the manifestation of signs determines individual hereditary factors that are transmitted from parents to descendants with gametes. Each factor can exist in two mutually exclusive forms – alleles. Hybrids get one allele from their father, another allele from their mother. Thus, in each pea plant, there are two allelic genes that affect the color of the seeds.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
