An analysis of the informativeness of received preparations of chromosomal material from immature cells of the spermatogenous series was carried out. A cytogenetic analysis of chromosomes from spermatocytes was conducted. On the basis of the conducted researches a method of estimation of the pupils on a chromosomal polymorphism of a sexual cell is offered and the methodical recommendations "Cytological methods of research of spermatogenesis of bulls-pedigrees" are developed. The study of the haploid chromosome set in immature sex cells makes it possible to analyze the causes of abnormalities in the spermatogenesis of the pediatricians and is a safe method of study, since it excludes surgical intervention in their testes.5481 Product Description popup.authors Типило Христина тарасівна Шабанова Яна Вікторівна popup.nrat_date 2020-04-02 Close
