HEREDITY OF SEX.
DAUGHTERS WHO "TAKE AFTER" THEIR FATHERS.
Lecturing at the Royal Institution, London, on "Heredity of Sex," Professor Bateson related some curious facts which had been discovered as tho result of examining several generations of a family in which colour blindness appeared. A colour-blind woman is very rarely found, and she is always the daughter of a colour-blind man. Her sons and daughters would be normal, And her sons' families would be normal, but if her daughters had sons they would bo found to bo normal and colour blind in equal numbers. A curious anomaly with reference to colour blindness, appeared in twins. They were twins exactly alike in appearance, and, as is always the ease in the circumstances, of the same sex, in this case girls. But one girl was colour blind and the other was not. No explanation of this exception had boon found. Professor Bateson said there was a popular belief that sons in certain resncete took after their mother? and daughters after their fftthers. Within a reasonable range of speculation this was so. As to tons taking after their mothers, they saw this in their own exporienco of their own families.
