Yepp, commercial gene pool keeps getting smaller, weird reproductive anomalies get more frequent...

Stinky, just cause I'm curious, were your twins showing up along a single line ( daughters of a single male that you'd pollinated) or is this starting to show up in commercial breeder lines?

Also, how well matched were phenos of twins? Seem like single male sample + multiple ovum, or zygote split?

Normally I'd assume that somebodies " twins" were the result of reaping what they sow, so to speak, but your technique's pretty clean ( ya geek).
