Test breeding
« on: June 10, 2019, 04:57:05 PM »
Okay, genetics gurus. When test breeding for a recessive trait, what would you say would be a good number of chicks to hatch from a pair of birds to know for sure??? This would be breeding an unknown (possible carrier) to a known homozygote to see if the one bird carries it. Thanks in advance.

I personally would be quite comfortable after 10 or 12 chicks, and nearly 100% certain with 20 chicks.   Of course if you hatch one chick and it displays the undesired recessive you would not have to hatch any more.
