the case might be, from each of two baskets.
Every individual is a sort of basket containing two beans, as it were.
It took one of these two beans from each parent and will give one to
each child.

With this picture of a bean lottery before us it is very easy to
understand how the colors of Andalusian fowls are inherited. When two
black fowls mate, the offspring must be black, because in this case each
parent basket contains a pair of black beans, so to speak, so that the
child taking one black bean from each basket will necessarily have a
black pair. For the same reason the child of two white fowls must be
white, but when a black and white fowl mate, the child takes a white
bean from one parent and a black from the other, its own color being
resultant or amalgam of the two, which in the case of the Andalusian
fowl is blue. Since every such hybrid child has this same combination of
a white and a black bean, all these hybrids are alike. All are blue. It
is important to remember that this hybrid blue is only a sort of
mechanical mixture of black and white, and that the black and white are
still separate beans, as it were.

But now suppose a hybrid or blue fowl to mate with a white. This means
that the child takes from the white parent or basket one of the two
white beans and from the blue parent or basket, one of the two beans, of
which one is white and the other, black; the bean taken from the first
or white basket must be white, but that taken from the second or blue or
hybrid basket may be either white or black. It is a lottery with an even
chance of drawing white or black. In the long run, half of the children
will draw white and half, black. Those which draw the white will, since
they also drew white from the other parent, be wholly white, but those
which drew the black will be blue, since they will have one black and
one white bean. We see, too, that the white child is just as truly white
as though it had not had a hybrid parent; for of the two elements or
beans which the hybrid carried, the black one was left behind untaken.
We see that the blue child is a hybrid exactly like its hybrid parent,
and not any new kind of cross between the blue and the white. In short,
the children of a blue and white are either the one or the other and not
a mixture. In the same way if a blue mates with a black, half of the
children will be black and half blue.

Finally we come to the mating of a blue with a blue. Here the lottery
