Where there is a human being, there are the opportunity and the duty of

education
Where there is a human being, there are the opportunity and the duty of
education. But our present great concern, as friends of learning, is
with those schools where children are first trained in the elements. If
in these we can have faithful, accurate, systematic, comprehensive
teaching, everything else desirable will be added thereunto. But, if we
are negligent, unphilosophical, and false, the reasonable public
expectation will never be realized in regard to other institutions of
learning.

We can best understand the laws governing the inheritance of traits by

taking a few concrete cases
We can best understand the laws governing the inheritance of traits by
taking a few concrete cases. The first case is that of an Andalusian
fowl. We shall consider the two species, pure bred black and pure bred
white, and confine ourselves to observing the inheritance of the single
characteristic, plumage _color_. Of course, as long as the black mate
only with the black their children will be black, and as long as the
white mate with white the children will be white. But if a white mates
with a black, the children will not be either black or white, but blue.
All will be blue. But the most interesting facts appear in the next
generation, when these hybrid blue fowls mate with black or white, or
with each other. The original of the cross between the white and the
black is an entirely new color blue, which may be considered a sort of
amalgam of black and white. But a cross between the blue and the black
will not be any new color, but will be either black or blue--and the
chances are even. That is, in the long run about half of the children
of the blue and black parents will be blue and half will be black. None
of the children will be white. So also crossing the blue with the white
will result in half of the children being blue and half, white. Still
more curious is the result of mating blue with blue. One might imagine
that in this case all the children would be blue, but only half will be
blue, while a quarter will be black and a quarter white.
