In this study the effects of selection in females only and in males only are compared for a character partly controlled by sex-linked genes.…”

SummarySelection for abdominal bristle number was done in six lines, three with selection in females only and three in males only_ Selection was equally effective (for a given selection differential) when carried out in either sex, even though more than one-third of the additive genetic variation was sex linked_ Most response in a given sex was found in the treatment selected in that sex. Relaxed lines failed to show fluctuating scores in the two sexes as predicted by Griffing (1965). Epistatic decay may have masked these effects.Formulae to predict response to selection, when there is a scale difference between the sexes and the genetic correlation between sexes is less than unity, are presented. Predictions of the relative response in males and females from these formulae were in good agreement with observed response in the single-sex abdominal bristle selection lines and in the abdominal bristle selection lines of Jones, Frankham, and Barker (1968).

“…The possibility of an X chromosome participation in a polygenie system cannot, however, be excluded, but the resultant effect on quantitative traits would be limited. Similarly, in the development of mammals and birds, Beilharz (1963) did not find conclusive evidence of sex linkage on reviewing 36 reports, except perhaps for the body weight of rabbits, mice and sheep. Moreover, the finding that adult males with Klinefelter's syndrome and adult girls with Turner's syndrome show correlation coefficients with their parents of the same level to those found with normal children suggests the genetic mechanisms are, for the most part, located on autosomes (Lemli and Smith, 1963;Brook et al, 1974Brook et al, , 1977.…”

“…Similarly, Cock and Morton (1963) reviewed the contradictory interpretations in the literature with respect to sex-linked and maternal effects in poultry, and suggested a diallel design for the purpose of detecting these effects. This problem was also recognized by Beilharz (1963).…”

SummaryThe diallel cross has been used frequently in plant experiments to partition the genetic variation into general and specific combining abilities of inbred lines. The statistical models developed for analysis of diallel crosses in plants have been used in a number of studies of diallel crosses in mammals and poultry, without due consideration to the presence and effect of the sex chromosomes.Two statistical models for the analysis of the modified diallel cross, one assuming maternal effects and one assuming no maternal effects, were compared for male and female progeny of both male homogametic species and female homo· gametic species. It was found that neither statistical model is adequate to separate the effects of sex·linked genes from both maternal and autosomal additive genetic effects when data on only one sex of progeny are analysed.Utilization of estimates from both statistical models provides a crude estimate of sex.linked, maternal, and additive autosomal effects only in the case of female progeny of male homogametic species such as poultry.
