Life table of Sogatella furcifera after treatment of the
parental generation with water (control) or sublethal concentrations (LC10, LC25) of triazophos.
However, it is very possible that mutation could cause enhancement in morphological traits and seed yield in the
parental generation, but transfer of these modified genes into subsequent generation may be futile.
This could be interpreted as a cohort effect of the gender revolution in the 1970s
parental generation. Despite these positive developments, however, the tendency for women to work part-time and for men to work full-time or more has gendered consequences over the life course.
These community differences condition the extent to which the advantages or disadvantages experienced by the
parental generation are transmitted to the subsequent generation.
The data sources were as follows: group discussions with Pakistani and Bangladeshi young people at different stages in the educational system and at an early stage of labor market participation; interviews with public and voluntary sector practitioners in employment-related support services; interviews with women from the young women's
parental generation; and national and local statistics on application and entry to higher education.
To test these hypotheses, we examined the frequencies of SNPs which occur in CYP21P at positions homologous to those we have reported previously in CYP21 in members of the
parental generation of the Centre d'Etude du Polymorphisme Humain (CEPH) families, and compared the frequencies of these SNPs in CYP21P with those at the homologous positions in CYP21.
Means for wing traits in the
parental generation were lower in the stress environment compared to the control environment (Table 1).
Symmetrical non-genetic maternal and paternal rearing host effects would also explain the observed differences in survivorship between the
parental generation and the final experimental generation [ILLUSTRATION FOR FIGURE 1 OMITTED].
The purpose of the current study was to investigate the effects of a 45[degrees]C heat shock applied to the WFT
parental generation on the life table parameters of the F1 generation.
A critical factor that heavily affects the result of oral sensitization studies is the unscheduled dietary pre-exposure of test animals and their
parental generation to the antigen under investigation.
These beetles will subsequently be referred to as the
parental generation. To create lines for generation 1, pairs were confined in a 35-mm petri dish (one pair per dish) containing either one V.
This generation's previous "failure to deidentify with their
parental generation" led to the "delayed disobedience" of 1968.
- In order to determine if the food ration of the
parental generation affected the next generation we examined 120 progeny from the parental study (5 strains x 2 food levels to
parental generation x 2 food levels to the second generation x 6 replicates).
Under arrhenotoky conditions, the longevity of adult females of the
parental generation exposed to 41[degrees]C was shortened significantly from 34.65 days in the control to 17.67 days after a 36 h heat shock ([F.sub.(5,12)] = 117.34, P = 0.0001) (Fig.
Thus, maternal effects provide a nongenetic mechanism by which environmental variation in the
parental generation affects the phenotype of their progeny (Riska et al.
