A heifer can't reproduce because of the testosterone from her twin brother affects her hormones and ability to grow normal reproductive organs. She is thus called a freemartin.
However, her brother is able to reproduce.
The heifer that has a 90% chance of being sterile. Sterility in the heifer is caused by the influence of testosterone from her twin brother (who is supposedly sharing the same placenta as her) that is excreted when he has began to form his sexual organs. This inhibits the estrogen that is secreted from her, and consequently makes her sex organs underdeveloped or become more like a male's organs than a females. Or, she may have both male and female organs, both of which are quite underdeveloped. Hermaphrodites (and freemartins) are sterile because of this.

Everything about COWS?
When Cows are younger they are called a Calf, when they get older they are called a heifer, and they are only considered a cow after they have had a calf and producing milk. A bull is not a cow. The difference between a bull and a steer is that a steer has had its testicles removed so it cant produce anymore. There is a common mis-conception about there stomach. They have been told to be having 4 stomachs but it is 1 stomach with 3 compartments. The Rumen, Omasum, Reticulum, and the Abamasom.

What do you call a heifer that cant reproduce. The heifer is not a twin.?
I would call her hamburger. Either that or a VERY expensive pasture ornament.This heifer may also be referred to as a cull because of this. It's best to get rid of her (turning her into the great food source as mentioned above), because she WILL turn into an expensive lawn ornament, or an animal that will take your money from you and give you nothing back in return!
