Freemartins
- In animal husbandry, cattle that are born exhibiting characteristics of both sexes are called freemartins.
- Freemartins are sterile female cattle that result from the twinning of a male and a female within the same uterus.
- This phenomenon occurs in approximately 90% of such twin pregnancies in cattle.
- The key reason behind the phenomenon is the exchange of blood between the male and the female foetuses during gestation.
- Genetically, freemartinism is attributed to the sharing of cells carrying the Y chromosome from the male twin with the female twin.
- This chromosome triggers the development of male reproductive organs ....
