Because the risk enhancement for women with many sisters but only one with breast cancer will be less than that for women with a single sister, who has breast cancer, it is possible that sibship
size could become a confounder in this cohort if relevant risk factors (e.
However, trends in the current study for both sibships
and spatial autocorrelation are toward older adults of each sex having undergone more complete dispersion to greater distances than younger adults.
5The socio-demographic and biological attributes of the recruited cases including parental consanguinity sibship
composition and family history of any congenital malformation are mentioned in Table-I.
In a 2007 article, we provided statistical support (based partly on a chi-square test of data assumed to conform to a binomial distribution) for the hypothesis that parental choice (family planning) seems likely to be responsible for more same-sex sibships
than unlike-sex sibships
in families of two.
They recruited 211 families consisting of 213 sibships
, with 287 sibling pairs that included 460 siblings (87% of sibships
consisted of two siblings, 19% had three siblings, and 3% had four siblings).
Granulomatous reaction to intradermal injection of lepromin (mitsuda reaction) is linked to the human NRAMP1 gene in Vietnamese leprosy sibships
Does the Gender Composition of Sibships
Affect Women's Educational Attainment?
2) In all the novels except Emma, an entanglement of three sibships
constitutes the plot (in Emma the third group consists of orphans: Frank Churchill, Jane Fairfax, and Harriet Smith; the Martin siblings are also on the sidelines).
Birth order and educational attainment in full sibships
Each experiment was initiated with larvae derived from three sibships
The accumulated body of research shows a special fascination with functions of the size of sibships
, their composition with respect to age or gender, and the position of individuals within their sibships
(Ernst and Angst 1983; Heer 1985, 1986; Blake 1989).
This chance was small because sibships
were generally large.
