A mutation in the age-1 gene in Caenorhabditis elegans lengthens life and reduces hermaphrodite fertility.
age-1(hx546) is a recessive mutant allele in Caenorhabditis elegans that results in an increase in mean life span averaging 40% and in maximal life span averaging 60% at 20 degrees; at 25 degrees age-1(hx546) averages a 65% increase in mean life span (25.3 days vs. 15.0 days) and a 110% increase in maximum life span (46.2 days vs. 22.0 days for wild-type hermaphrodites). Mutant males also show ...
متن کاملA genetic analysis of hermaphrodite, a pleiotropic sex determination gene in Drosophila melanogaster.
Sex determination in Drosophila is controlled by a cascade of regulatory genes. Here we describe hermaphrodite (her), a new component of this regulatory cascade with pleiotropic zygotic and maternal functions. Zygotically, her+ function is required for female sexual differentiation: when zygotic her+ function is lacking, females are transformed to intersexes. Zygotic her+ function may also play...
متن کاملSex Determination: Ways to Evolve a Hermaphrodite
Most species of the nematode genus Caenorhabditis reproduce through males and females; C. elegans and C. briggsae, however, produce self-fertile hermaphrodites instead of females. These transitions to hermaphroditism evolved convergently through distinct modifications of germline sex determination mechanisms.
متن کاملPhenotypically plastic adjustment of sex allocation in a simultaneous hermaphrodite.
Sex allocation theory for simultaneous hermaphrodites predicts an influence of the mating group size on sex allocation. Mating group size may depend on the size of the group in which an individual lives, or on the density, but studies to date have not distinguished between the two factors. We performed an experiment in which we raised a transparent simultaneous hermaphrodite, the flatworm Macro...
متن کاملInteractions of socioeconomic determinants, offspring sex preference, and fertility behaviour
Using path anaysis and the 5 per cent PUMS data of the 1990 and 2000 [US] censuses, this study examines: (1) the correlation between Chinese-American sex preference for children and their fertility behavior; and (2) the interaction between the sex preference and its socioeconomic determinants. Of the normative and non-normative factors investigated in this study, offspring sex preference is the...
