Summary
Intersexuality is rare in domestic animals, with this study classifying cases in dogs, cattle, goats, sheep, and horses by karyotype. Findings detail XX, XY, and XX/XY intersex conditions across these species.
Area of Science:
- Veterinary Genetics
- Reproductive Biology
- Animal Science
Context:
- Intersexuality, characterized by variations in sex development, is infrequently documented in domestic animal populations, excluding bovine freemartinism.
- Previous reports on intersex conditions in domestic animals are limited, necessitating further detailed classification and analysis.
Purpose:
- To classify and describe reported cases of intersexuality in domestic animals, including dogs, cattle, goats, sheep, and horses, based on their karyotype.
- To provide a comprehensive overview of the different intersex conditions observed, such as pseudohermaphroditism and true hermaphroditism, across various species.
Summary:
- This study details intersexuality cases in domestic animals, categorizing them by karyotype (XX, XY, XX/XY).
- XX intersexes included polled male pseudohermaphrodites and true hermaphrodites in goats, and female pseudohermaphrodites in dogs.
- XY intersexes comprised a true hermaphrodite dog, male pseudohermaphrodites in other dogs, gonadal dysgenesis in mares, a female pseudohermaphrodite cow, and XX/XY intersexes in ovine freemartin cases.
Impact:
- Enhances understanding of the genetic and developmental basis of intersexuality in common livestock and companion animals.
- Provides valuable data for veterinary diagnostics, genetic counseling, and reproductive management strategies in affected domestic animal populations.
- Contributes to the broader scientific knowledge of sex determination and differentiation mechanisms in mammals.
