Exempel på sib

• Sib-infection experiments were carried out to test the relative effects of selfing and outcrossing on the infection of progeny with parental viruses.

• The difference is not a function of the index boys without sibs being younger than those with sibs.

• In fraternals, however, an effort to out-strip the sib was the usual reaction in a competitive situation.

• Apart from the length of gestation, birth weights of singleton sibs may be differentially affected by many environmental factors.

• The current sample consists only of sib-pairs, so we obtained an index of familial vulnerability of an individual from their sibling's trait values.

• It should be noted that in the case of families of size 2, this selection method is the same as selecting discordant sib-pairs.

• For all lines, the maximum likelihood procedure decomposes families into multiple families of sib-pairs.

• Therefore, even with the least intense selection, some sib pairs were not used in the analysis - something that resulted in more biased parameter estimates.

• The latter effect will, to an uncertain extent, be offset by the consideration that younger sibs may not yet have reached adult age.

• This is because of the high computational expense for eight sibs under this method.

• The major difference between this study and earlier ones is that it focuses on families larger than two sibs.

• Effect of excluding sib matings on inbreeding coefficient and effective size of finite diploid populations.

• Continuous line is with a constant number of sibs, dashed line is with a variable number of sibs as described in the text.

• The items which do not distinguish patient from sib do not, on the whole, correlate with the dysthymia items in the healthy sample.
