Summary
-
1.
The effects of a series ofr alleles on embryonic development in crosses of mutant to mutant have been described.
-
2.
Development inr embryos is normal until primary organogenesis is complete, but there is a complete cessation of differentiation between the thirteenth and sixteenth hours of development. Processes of differentiation which occur after this period are delayed, but occur normally.
-
3.
Quantitative differences are observed in the patterns of damage ofr 39 andr 41. These reflect, in direction of degree of severity, quantitative differences which have been observed between the two in fertility, fecundity and production of abnormal eggs.
-
4.
The presence of some males in crosses ofr females to non-r males has been interpreted as evidence of a positive effect on development of supernumerary sperm in the egg cytoplasm.
-
5.
The effects on development ofr are compared with those of two other sex-linked genes—fu anddor—which exhibit a similar type of female-sterility.
-
6.
In the light of increasing interest in the genetic potential of the cytoplasm the significance of nuclear-cytoplasmic interactions involved in the present study is commented upon.
