Many mums-to-be are convinced that the angle that this nub is resting at the ‘angle of the dangle’ at their week scan, can determine the sex of the child. Skull theory Another popular theory that says you can tell your baby’s sex from the shape of their skull on the week scan. Or smaller compared to the rest of the body? Some say if you look closely this will give your baby’s gender away. Three lines Far from being seen as just a theory, the three lines or ‘potty shot ‘ on a scan are actually often use my by midwives to tell the sex of your baby and is pretty accurate. The difference between this one and the others mentioned, though, is that you’ll need to wait until your week scan to see it – or perhaps week scan if you go to a private clinic.

Twin studies[ edit ] A number of twin studies have attempted to compare the relative importance of genetics and environment in the determination of sexual orientation. Self reported zygosity , sexual attraction, fantasy and behaviours were assessed by questionnaire and zygosity was serologically checked when in doubt. Other researchers support biological causes for both men and women’s sexual orientation. Women showed a statistically non-significant trend to weaker influence of hereditary effects, while men showed no effect of shared environmental effects.
The use of all adult twins in Sweden was designed to address the criticism of volunteer studies, in which a potential bias towards participation by gay twins may influence the results; Biometric modeling revealed that, in men, genetic effects explained. Corresponding estimates among women were. Although wide confidence intervals suggest cautious interpretation, the results are consistent with moderate, primarily genetic, familial effects, and moderate to large effects of the nonshared environment social and biological on same-sex sexual behavior.
Nonetheless, it is possible to conclude that, given the difference in sexuality in so many sets of identical twins, sexual orientation cannot be attributed solely to genetic factors. Gringas and Chen describe a number of mechanisms which can lead to differences between monozygotic twins , the most relevant here being chorionicity and amniocity. Monoamniotic twins share a hormonal environment, but can suffer from the ‘twin to twin transfusion syndrome’ in which one twin is “relatively stuffed with blood and the other exsanguinated”.
In Dean Hamer and colleagues published findings from a linkage analysis of a sample of 76 gay brothers and their families. Gay brothers who showed this maternal pedigree were then tested for X chromosome linkage, using twenty-two markers on the X chromosome to test for similar alleles. This was popularly dubbed the “gay gene” in the media, causing significant controversy. Significant linkage was also detected in the pericentromeric region of chromosome 8, overlapping with one of the regions detected in the Hamer lab’s previous genomewide study.
