Hermaphrodite with Mosaic
SIR,-In a recent review de Grouchy 1 compiles the following karyotypes described in true hermaphroditism: 46 XX, 46 XY, 46 XX/46 XY, 45 XO/46 XY, 46 XX/47 XXY, 46 XX/47 XXX, 46 XX/46 XY/45 XO, 46 XX/47 XXY/ 49 XXYYY, and 45 XO/46 X isoY/47 XY isoY. We have studied the chromosomes of a true hermaphrodite with a new mosaicism, 46 XX/46 XY/47 XXY, which might throw some light on the possible multi...
متن کاملHermaphrodite cell-fate specification.
There are two sexes in C. elegans, hermaphrodite and male. While there are many sex-specific differences between males and hermaphrodites that affect most tissues, the basic body plan and many of its structures are identical. However, most structures required for mating or reproduction are sexually dimorphic and are generated by sex-specific cell lineages. Thus to understand cell fate specifica...
متن کاملElectric Impedance of Arbacia Eggs
The alternating current resistance and capacity of suspensions of unfertilized and fertilized eggs of Arbacia punctulata have been measured at frequencies from 10(3) to 1.64 x 10(7) cycles per second. The unfertilized egg has a static plasma membrane capacity of 0.73 microf./cm.(2) which is practically independent of frequency. The fertilized egg has a static membrane capacity of 3.1 microf./cm...

متن کاملChromosome mosaicism in a hermaphrodite.
The chromosome complement in 27 patients with convincing evidence of hermaphroditism has now been investigated. A normal female karyotype (44 autosomes + XX) was reported in I7 cases (Bregman, Bregman, Cushner, and Woods, I963; de Assis, Epps, and Bottura, I960; Dewhurst, Warrack, and Casey, I963; German, Bearn, and McGovern, I962; Gordon, O'Gorman, Dewhurst, and Blank, I960; Harnden and Armstr...
