Can you explain how the chocolate gene works, 'cause I haven't a clue!
-Kathy
chocolate is a sex linked recessive gene. Basically this.means it takes 1 copy to make a female chocolate and 2 copies to make a male chocolate. A male can carry chocolate and not show it while a female can only show chocolate if she carries it. If she doesn't show it, then she doesn't carry it. No one can ever have a chocolate split pullet. This is the possible genetic crossings from chocolate and black.
Chocolate Male X Chocolate Female = 100% Chocolate
Black Male X Chocolate Female = 50% Black Males carrying Chocolate, 50% Black Females
Chocolate Male X Black Female = 50% Black Males carrying Chocolate, 50% Chocolate Females
Black Male carrying Chocolate X Chocolate Female = 25% Chocolate Males, 25% Black Males carrying Chocolate, 25% Chocolate Females, 25% Black Females
Black Male carrying Chocolate X Black Female = 25% Black Males carrying Chocolate, 25% Black Males, 25% Chocolate Females, 25% Black Females.
