Parentage and sibship
inference from multi-locus genotype data under polygamy.
Significantly, it produces a full sibship
ratio of 10m for Joe (and it shows that Joe and the Crime 1 sample have the same set of Y-STRs).
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.
This could prove quite fruitful in the ongoing discussions regarding sibship
size and resource dilution theory (Steelman et al.

Austen's position in her sibship
is significant: she was the second daughter and seventh-born child in a group consisting of one absent and disabled sibling, three big boys studying with her father, and then a nursery of girl, boy, girl, boy.
According to this explanation, the gender of the siblings of the child is important because it is the child's 'reference group', and the child adopts the traits of his/her sibship
