Abstract

Quantitative signs can be divided into two groups according to their heredity: the first group of signs (productivity and number of coals) is influenced by a large number of polygens, which manifest the effectiveness of strong epistatic and dominant alleles. Paratipic variants in this case are high, with a low degree of heredity. The second group of signs (breast enlargement, fiber length and output, etc.)) controlled by a low number of polygens with a weak effect. The paratipic variant in this case is somewhat smaller and the heredity is somewhat higher. As can be seen from the data obtained in our experiments, the degree of equilibrium of the sign in different soil-climatic conditions is variable, and the influence of genes on the development of the sign is changing. Under the influence of adaptation to the conditions of the external environment, there is a shift in indicators to a positive one.The fiber output sign has a relatively high degree of heredity within most polygenic signs.
