Shifting genetic patterns in anencephaly and spina bifida. Open in a separate window The number of adverse outcomes or miscarriages is consistent with an increase in interbirth interval. Although these results are suggestive for an increase in miscarriages in the maternal lineage, this difference did not reach statistical significance.
The interbirth interval for paternal aunts and uncles is 3. Neural tube defects in the sample of genetic counselling. Sex ratios of affected and transmitting members of multiple case families with neural tube defects. This is notably true in the culture of Korea. Although these results are suggestive for an increase in miscarriages in the maternal lineage, this difference did not reach statistical significance. Results of segregation analysis and linkage studies suggest that this model is appropriate. In the long run, however, because of this increased exposure of deleterious recessive alleles to natural selection , their frequency decreases more rapidly in inbred population, leading to a "healthier" population with fewer deleterious recessive alleles. So shall no inheritance remove from one tribe to another tribe; for the tribes of the children of Israel shall cleave each one to its own inheritance.

The sex ratios suggest an excess of females in the overall NTD dataset, which becomes greater with increasing severity. This hypothesis assumes that there is a single dominant gene with reduced penetrance segregating in these families and that all affected individuals presented with an NTD as a result of receiving the same genetic susceptibility. Professor Neil Small from the University of Bradford, who co-led the research, said:
