Проанализированы данные 6927 ягнений от маток пород дорпер, романовская и эдильбаевская. Общее соотношение полов составило 49,6% баранчиков и 50,4% ярок, что соответствует теоретическому паритету 1:1. Хотя в отдельных породах наблюдались колебания (57,0% баранчиков у эдильбаевской против 42,3% у романовской), статистически значимой связи не выявлено (p=0,149). Породная принадлежность не является значимым фактором формирования пола потомства. Для объяснения вариабельности необходимы дальнейшие исследования других факторов.</p></abstract><trans-abstract xml:lang="en"><p>The influence of sheep breed on the sex ra- tio of offspring was studied. Data from 6,927 lambs from Dorper, Romanov, and Edilbaevskaya ewes were analysed. The overall sex ratio was 49.6% male lambs and 50.4% fe- male lambs, corresponding to the theoretical parity of 1:1. Al- though fluctuations were observed in individual breeds (57.0% male lambs in Edilbaevskaya versus 42.3% in Romanov), no statistically significant relationship was found (p=0.149). Breed is not a significant factor in determining the sex of off- spring. Further research on other factors is needed to explain the variability.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>овцы</kwd><kwd>соотношение полов</kwd><kwd>порода</kwd><kwd>пол потомства</kwd><kwd>хи-квадрат</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sheep</kwd><kwd>sex ratio</kwd><kwd>breed</kwd><kwd>sex of offspring</kwd><kwd>chisquare</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дедкова А.И., Сергеева Н.Н.
