Not usually, only the heifers are affected by infertility due to twinning.
No. Only a heifer calf twinned to a bull calf will be infertile, not twin heifer calves.
95 percent of the time they are, they are called Freemartins
No. A heifer would only be sterile if she was twinned with a bull calf.
A bull calf.
Only if the twin is a heifer and if that twin has been tested negative for being a freemartin (IF she had been twinned with a bull calf). Twin heifers are both highly likely to get pregnant when they reach puberty.
No. Only a heifer calf twinned to a bull calf will be infertile, not twin heifer calves.
It doesn't work that way. A heifer calf is only infertile if she is twinned with a bull calf and if her and that bull calf share the same placental tissues. In most cases such twins are fraternal, but simply stating that fraternal twins versus maternal twins are more prone to infertility than the other is stating falsehoods.

They should've dropped before the bull calf was born. If not then you have a crypto bull on your hands, and an infertile one at that.
No. A heifer would only be sterile if she was twinned with a bull calf.
You could call it a heifer, or a twin heifer if the sibling is also a heifer, or a freemartin if the heifer's sib is a bull calf.
A bull calf.

Yes.
Bull calf if intact; steer calf if castrated.
Neither. Both calves will be fertile. You will only get a sterile female calf if she's born to a twin bull brother.
