Were it otherwise, I should certainly mope myself into a green melancholy over the fact, the most dismal fact on earth, that brachycephalism is a Mendelian dominant. No use lamenting. True. But the sage will reserve to himself the right of cursing.
It is no intention of the writer of this paper to describe the Mendelian theory, which is well known, at least to all biological readers, though one or two points in connection with it may yet have to be touched upon.
It is indeed an absurdity to the "pure line" Mendelian, but not to one who appreciates the fact that Mendelian units are subject to quantitative variation sometimes continuous, sometimes discontinuous. An example of the former is found in the hooded pattern of rats, of the latter in albinism and other Mendelizing characters which assume multiple allelomorphic conditions.
Not a few writers apparently think of patriotism as a fixed trait of the human organism, even as a kind of mendelian character unrelated to other social qualities. This trait antagonizes social progress, but it is preserved because of secondary values which it represents, such as moral or æsthetic values. According to these views patriotism may be complex, but it acts like a unitary character.
In Mendelian language the male is homozygous, so-called "pure" as regards this character. But the female is heterozygous, "impure" in the sense that her femaleness depends upon the dominance of the factor for femaleness over the factor for maleness, which also is present in her. In the Mendelian terminology, she is an instance of impure dominance.
"I know my point is Carlylean, but that does not invalidate it. Hero-worship is a very good thing. I am talking, not as a mere scholastic, but as a practical breeder with whom the application of Mendelian methods is an every-day commonplace." "And I am to conclude," Hancock broke in, "that a Hottentot is as good as a white man?" "Now the South speaks, Aaron," Dick retorted with a smile.
This question of compatibilities is illustrated very strikingly by the case of the worker-bee. There is as yet no purely Mendelian interpretation of this case, Mendel's own laborious work upon heredity in bees having been entirely lost, and practically nothing having been done since.
Mendelian phenomena of inheritance, confirmed and extended by numerous workers with plants and animals, prove that in many cases portions of the streams of germ plasm that combine to form the hereditary content of organisms may retain their individuality during embryonic and later development, and that they may emerge in their original purity when the germ-cells destined to form a later generation undergo the preparatory processes of maturation.
A brisk talk sprang up between Capes and Mr. Stanley, to which the two ladies subordinated themselves intelligently. The burning topic of the Mendelian controversy was approached on one or two occasions, but avoided dexterously; and they talked chiefly of letters and art and the censorship of the English stage. Mr.
But regarding a factor as something which, although it may be divided, neither grows nor dwindles, neither develops nor decays, the Mendelian cannot conceive its beginning any more than we can conceive the creation of something out of nothing.
