Abstract
When nuclei containing the burnsi gene are transplanted to wild-type cytoplasm, the resulting progeny are burnsi progeny. The burnsi gene therefore serves well as a nuclear marker. Offspring from a common blastula nuclear donor display striking similarities in pigment pattern. Environmental fluctuations, which may have included variations in recipient egg cytoplasmic quality and other subtle variations not easily controlled, were not sufficient to alter the intrinsic genetic control of the pigment patterns of these isogenic groups of frogs.
