In males, we expect autosomal DNA to be sequenced twice as often as X DNA because they have a 2 1 ratio in the genome.
In a second experiment, females were offered a choice between a sib and a non-sib male; we expected that females should be able to avoid sib matings and should prefer to mate with non-sib males.
As all individuals sequenced to construct the genome were male, we expect no difference in the quality of the assembly of the Z chromosome versus the autosomes (Xia et al. 2004).
Given that previous studies have reported higher rates of ADHD among males [ 51– 55], we expected to find a smaller proportion of female patients with symptoms of ADHD.
Given this, it is likely that we have underestimated the prevalence of HPV, particularly in our sample of males, although we expect the distribution of HPV types to be accurate, as the assay validation study demonstrated a similar distribution of HPV types in urine compared with gold standard specimens.
To the extent that the expression of male ornaments is a signal of male quality, we expect females to increase their investment when paired to highly ornamented males.
If stress is the main trigger of migraine in females but not in males, we can expect females to have greater comorbidity of migraine and TTH, which is also triggered by stress.
If female responsiveness mostly depends on the relative attractiveness of males, we might expect a negative correlation between a female's responsiveness to her partner and her responsiveness to extra-pair males.
This result was surprising because these populations had increased in male fitness and we expected elevated rates of courtship towards females to be part of that response.
Males are under strong selection to provide a gift [ 19]; therefore, we expected males to offer a worthless (non-nutritive) item if no prey is available.
