Any organism has a lot of signs, and the number of chromosomes is small. Therefore, there must be many genes on each chromosome. Such genes are called linked to each other. They form a clutch group. In other words, each chromosome is nothing but a linkage group, and since homologous chromosomes carry genes responsible for the development of the same traits, genetics include both paired chromosomes. The number of linkage groups corresponds to the number of chromosomes in the haploid (single) set. So, for example, a person has 46 chromosomes — 23 linkage groups.
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.
