Further experiments on the cross-breeding of two races of the moth acidalia virgularia

Abstract

A communication on the heredity of the two. forms of this species was read to the Royal Society on February 25, 1909. In that paper Messrs. Prout and Bacot gave an account of a large number of broods of this moth reared by them for nine generations. At the end of the paper they mentioned that they had handed to- Mr. W. Bateson ova produced by pairings in generation F 10 . It was the larvae derived from these ova which Mr. Bateson gave into my charge in February, 1909.
