Description:
‘Dear Professor Pearson,
The case of the offspring of 2H276 becomes much more remarkable in view of the fact, mentioned in your letter of 3rd inst., that the hybrids which produced the aberrant albinos were the offspring of a waltzer and extracted albinos.
I should think it is quite likely that this is the only mating of extracted albinos together, with such ancestry and the experiment must certainly be repeated. I think it is quite likely that we shall get this result again in view of the fact that hybrids from extracted albinos & waltzers produce far less than ¼ albinos.
I think I could probably find out about the crossbreeding from Steer’s as I have his letters. But tho I have had definite assurances as to the purity of the albinos from some of the other people, I have had reason to doubt their statements in one or two cases. For example the albino parent of [illeg.] 12 was, I believe, stated to be pure but produced 3 yellow (with black eyes) x 2 greys; a result which I have never got from albinos which I know to be pure by breeding them myself.
But I will look thro’ Steer’s letters when I get back to to Oxford, in about 5 days time. I am yours faithfully,
A.D. Darbishire’
