... carry a partial duplication of the X chromosome such that X/A ≅ 0.7, they develop as intersexes that are sexually mosaic. We have analyzed these mosaics using Nomarski microscopy and in situ hybridization to obtain information on whether sex determination decisions can be made independently in different...

... to at least 12 days post-fertilization. Approximately 18 % of injected fish raised to maturity exhibited CAT activity in their fins, and approximately 5 % of injected fish became stable germ-line transformants. Breeding studies indicated that although transgenic founder fish were frequently germ-line mosaics...

...R. W. Jeffery; Glen Jeffery; B. M. Cattanach ABSTRACT Female mice showing albino mosaicism due to an X-autosome translocation [Is(In7;X)Ct] have been studied in order to investigate the relationship between the distribution of melanin and the formation, early in development, of the abnormally small...

...Lalji Singh; Shoichi Matsukuma; K. W. Jones ABSTRACT A study, by means of Y-chromosome-specific repeated DNA probes, of mouse (ST) with small testes is reviewed. Mouse ST was shown to be a somatic mosaic of 10 % XY and 90 % XX cells. The cellular composition of the azoospermie testis reflected...
