Hey all! Hope you're ready for the holidays because here they come!! :th
And then it's that special time of year where our feather babies turn crazy and make babies of their own!

So, today's question is...

If Chance the gander and BB goose hatch babies, will they be auto sexing?

Chance (M)= Cotton Patch= auto sexing color

BB (F)= Saddleback Pomeranian= non auto sexing color

No. If the goose/gander colors were switched you might get sex-linked hybrids, but not this way.

Autosexing works because of a gene on the sex chromosomes: male gets two copies, female gets one, so they look different.

Sex-linked hybrids work when a goose gives one copy of a gene to her sons, and none to her daughters, so they look different. In this case your gander has the sex-linked gene needed, and he'll give one copy to each baby no matter what their sex, so it doesn't tell you anything.
