Activity of a gene in transplanted oocytes in the annelid,Platynereis.

Abstract

Pteridine eye pigment, indicative of the activity of theor ⁺-allele, was observed inor/or larvae ofPlatynereis, derived from transplantedor ⁺/or oocytes. These heterozygous oocytes had grown up inor/or hosts, themselves deficient in pteridine pigment synthesis. It is therefore concluded that theor ⁺ gene product, responsible for pteridine pigment synthesis in theor/or larvae, had been synthesized by the oocyte genomes.
