call duck colours???

[olpoll]

hello there,
ive recently bread some call ducks i took eggs from a female apricot and a female blue fawn, all the eggs were fertilized by the same apricot drake
my question is.....
the ducklings are now feathering up and obviously i have pure apricot ducklings but i appear to also have pure blue fawns when i thought i would end up with a blue fawn/apricot cross
im not complaining as ive bread them to sell so im thrilled that the colours are all pure, is this normal? and how come i haven't got crosses?

Hmmm, well the genotype on an apricot is m^d /m^d Bl /Bl and a blue fawn is M+/M+ Bl /bl+ .
so all your apricot crosses should come out apricots, but your blue fawn crosses will not be blue fawn. The blue fawn crosses for first allele will give you a dusky gene on each , but they will have the M+ dominant. Basically your blue fawns genotype looks like M^d/M^d and then either 50% Bl/Bl or and 50% Bl/bl. Basically, they won't be true breeding. Im not sure how the ducky series will look as adults, but they aren't true breeding blue fawns. That's how I understand it, anyway.

so the blue fawns will be a apricot/blue fawn mix but look more like blue fawns than apricots?
sorry but its all a bit confusing
mums an blue fawn dads an apricot ducklings look like mum and nothing like dad?

so the blue fawns will be a apricot/blue fawn mix but look more like blue fawns than apricots? Yes, because the genes for color the blue fawns carry are dominant(noted by capital letters)
sorry but its all a bit confusing
mums an blue fawn dads an apricot ducklings look like mum and nothing like dad?Like I said, I'm not sure what the dusky gene will end up looking like as they mature, but they should mostly look like mom because her genes are dominant. Second generation will look slightly more like a mix.

thanks for explaining its all getting a bit clearer now
