Heritability estimates of NEB and AFB for the pooled sample of women from the UK and the Netherlands using information from about 1 million SNPs.

a: standardized by country and log transformed to adapt the distributionb: standardized by countryc: p-values are based on likelihood-ratio tests, the reference model constraints genetic effects to be 0; Please find estimates of untransformed variables in S2 Tabled: The N for age at first birth is larger than for number of children ever born. The reason is that only women with completed fertility history are included for the latter (for discussion see material and methods and Table 1.).Heritability estimates of NEB and AFB for the pooled sample of women from the UK and the Netherlands using information from about 1 million SNPs.
