Attempts at Locating the Site of Action of Genes Affecting Behaviord out (i) whether any of the behaviors are governed by single cells or single clones, (ii) how many distinct, independently controlled differences underlie the behaviors we measure, and (iii) which tissues control the behaviors.

相反放置

Reproduction in Single-Sex Chimerasponents suggest that this expectation is fulfilled (McLaren 1976). The problems of XX ? XY animals, both from the point of view of sexual differentiation, and as regards the fate of their germ cells, are considered elsewhere in this volume. In this paper I shall restrict myself to single-sex chimeras and their germ cells.

In short, do cells of the mutant phenotype remain unchanged, or do they react to the new environment and participate in normal development? With respect to the T/t locus, this question has been approached once before, in 1964 by Mintz for the . gene.

XY mouse chimeras have led to the conclusion that the XX chromosomal constitution precludes differentiation of germ cells into spermatozoa; and they have provided some evidence that the XY constitution may be compatible with oogenesis.
