Abstract
The use of genetic tasks is due to a number of reasons: the impossibility of crossing in the case of studying the inheritance of lethal genes; the duration of pregnancy and the time of puberty, when it is possible to carry out another crossing and get the next generation, especially if we are talking about organisms with a long period of growth and development; the economic inexpediency of conducting- performing an analytical crossing, in the case when animals are kept exclusively for the detection of recessive genes, and the probability of the gene's action is no more than 50 %. The above problems can be circumvented by creating model situations in the form of setting and solving genetic problems. The methodology of the approach to their solution remains poorly developed, and therefore this issue is relevant.
