Beneden (B Beneden) elaborated in detail at Liege University fleming In 1887, he successfully discussed two basic facts about chromosomes. First, the number of chromosomes in different cells in the body remains the same, and there are certain numbers of chromosomes in various organisms (for example, it is known that each cell of human beings contains 46 chromosomes). In addition, he found that in the process of formative cells, namely, eggs and sperm, chromosomes do not replicate before the first division of cells. Each egg cell and sperm cell contains only half of the usual number. This is in line with Mendel's law of inheritance. If chromosomes exist in pairs, if every genetic gene exists in pairs (there is one on each chromosome of a pair of fixed chromosomes), then every parent will transmit one such gene to a personality cell. When the egg cell combines with the sperm in the process of fertilization, the number of chromosomes will return to normal, and the offspring will again have a pair of genes, one from the female parent and the other from the male parent. Once Devulis rediscovered Mendel's posthumous works, all this was clearly explained.
