If these are bred together the result in F2 is equal numbers of red-eyed and white-eyed females, and equal numbers of red-eyed and white-eyed males. The ration of dominant to recessive is 2 to 2 instead of the usual Mendelian ration of 3 to 1.
We would also find monkeys and apes, the recessive species descended from man. Even new sciences, founded by evolutionists, bear witness against their theory. Mendel's Inheritance Law is one, as we have seen; Biometry is another. It was proposed and advocated by Sir Francis Galton, a cousin of Charles Darwin.
Is there a quantitative addition of internal glandular tendencies in the germplasm, or a more complex rearrangement dependent upon reactions between all the internal secretions? The term endocrine dominants brings up the inquiries of Mendelism, and the relation of Mendelian conceptions of dominant and recessive to the internal secretions.
Now I am well assured that if we could study not only the patencies but also the latencies of individuals of both sexes, we should find that they vary equally. Women, as individuals, appear more similar than men, but as individuals conveying latent or "recessive" characters which will appear in their children, especially their male children, they are just as various as men are.
In our expansive moments we want to dominate and control everyone and destroy every unlikeness to ourselves; in our recessive phases our homes are our castles and we want to be let alone. Now all law, all social order, all custom, is a patch-up and a concession to this separating passion of self-insistence. It is an evasion of conflict and social death.
His treatment of the data is also cautious but thorough, so that when he works his way to a conclusion it stands firmly established. The conclusions reached are numerous and important, but the one of greatest theoretical interest is this, that feeble-mindedness is inherited as a simple recessive Mendelian unit-character.
They distinguish between "dominant" and "recessive" qualities, and they establish cases in which parents with all the dominant characteristics produce offspring of recessive type. Recessive qualities are constantly being masked by dominant ones and emerging again in the next generation.
This is evidence that the female produces two kinds of eggs, one male producing and the other female producing. With regard to the ordinary form of colour-blindness, Bateson's first explanation was that it was like the horns in the cross-bred sheep, dominant in males, recessive in females. About 4 per cent. of males in European countries are colour-blind, but less than 1/2 per cent. of females.
McClure's was not, speaking biologically, a new species at all; it was only a mutation in which the recessive traits of the old magazine became dominant while the invaluable type was preserved. To speak more plainly, the literary magazine, as America knew it, had always printed news, matured news, often stale news, but still journalism. Read any number of Harper's in the 'seventies for proof.
When the division in the gametes of the recessive individual takes place its gametes all contain the recessive character. Thus, if we indicate the dominant character by D and the recessive by d, the constitution of the two individuals is Dd and dd. The gametes they produce are D+d and d+d, and the fertilisations are therefore Dd, Dd, dd, dd,
