Leghorns carry a dominant gene that shuts off the brown... so even though the crossed chicks have the brown DNA the Leghorn Gene just shuts it off like throwing a switch (the DNA is there just shut off)... now if you crossed the chicks with each other enough you could get a few hens that maybe did not carry that Leghorn gene. On page 2 of the thread there is a link to a paper (I am still reading through it myself as it has allot of info to digest on this) but my understanding as of right now is that the Leghorn gene is dominant and also there are some pesky recessive genes also that shut the browning genes down too in birds. Check out the paper it is really good.
Thank You. Great info. Exactly what I was searching for.
