To determine if male copulation success was similar for half brothers, the cumulative copulation success of each son (= proportion of encounters won against all competitors) was analyzed using ANCOVA with the father's identity as a random factor and the son's size as a covariate.
Because most of the Y chromosome remains unchanged from father to son, the proportions of Sephardic and Moorish ancestry detected in the present population are probably the same as those just after the 1492 expulsions.
Because most of the Y chromosome remains unchanged from father to son, the proportions of Sephardic and Moorish ancestry detected in the present population are probably the same as those just after the 1492 expulsions, assuming no further emigrations since then.
Relative reproductive rate (Equation 4) corresponds to ω = (f, 0, 1 − f, 0 ) q (0, f, 0, 1 − f ) q = η f,1 + η m,1 2 in which v m = (f, 0, 1 − f, 0) and v r = (0, f, 0, 1 − f) reflect that the focal migrant and the focal resident each produce daughters and sons in proportions f and (1 − f).
Rachel Condry found that APV occurred across the social spectrum and that while it is more commonly against mothers by sons, a significant proportion of fathers were victims and daughters perpetrators.
Quite literally in the case of his guest soprano sax player dad Rickey Washington, "the man who taught me everything I know", who stands dwarfed beside his nightclub bouncer-proportioned son to help lay down some creamy horns with trombonist Ryan Porter over the mellow opening strains of Re Run.
We found that both the concentrations of all SON fractions and the proportion of more stable SON increased with increasing aridity index (AI, defined as mean annual precipitation/potential evapotranspiration).
There are females that produce almost exclusively daughters, females that produce sons in very high proportion and females that produce the two sexes in intermediate ratios.
Mussel females are of three types, those that produce almost exclusively daughters, those that produce sons in very high proportion and those that produce the two sexes in intermediate ratios.
We used a generalized linear logistic model with a logit link function [35] to test if offspring sex ratio differed with the source of wealth using the proportion of sons as the response variable, and gender and wealth-source as factorial predictors.
LMC theory predicts that the proportion of sons increases with increasing numbers of females in a patch.
