Natl. 35, 1018. Proc. Although the molecular understanding of genetic variation influencing facial morphology is improving, the use of DNA as a prediction tool is still a long way off. In a female, the width is roughly the same proportion, but the foot is just longer than the face is high, and the hand is at most 3/4 of the same height. 33:245. 6:737. doi: 10.3389/fpsyg.2015.00737, Bird, A. Hum. Biol. 67, 261268. Predominantly genetic influences have been reported for anterior face height, relative prominence of the maxilla and mandible, width of the face/nose, nasal root shape, naso-labial angle, allometry and centroid size (Carels et al., 2001; Carson, 2006; Jelenkovic et al., 2010; Djordjevic et al., 2013a,b, 2016; Cole et al., 2017; Tsagkrasoulis et al., 2017).

The determination of facial appearance, health history and future health risk from DNA is has great potential (Claes et al., 2014; Kayser, 2015; Toom et al., 2016) but caution should be expressed with respect to assumptions, interpretation and individual confidentiality as there is a significant threat to an individual in obtaining healthcare insurance (Hallgrimsson et al., 2014; Idemyor, 2014; Toom et al., 2016). doi: 10.1016/j.ajodo.2007.01.037, Kau, C.

Facial masculinity does not appear to be a condition-dependent male ornament in humans and does not reflect MHC heterozygosity.

Previous studies have identified genes associated with both nsCL/P and facial phenotypes; such as variation in MAFB which is associated with face width in normal variation (Beaty et al., 2010, 2013; Boehringer et al., 2011; Liu et al., 2012; Peng et al., 2013; Shaffer et al., 2016).

Expression of chick Barx-1 and its differential regulation by FGF-8 and BMP signaling in the maxillary primordia. The timing, vectors and duration of surges in facial growth tend to be different for males and females and between populations contributing to overall facial variation (Kau et al., 2010; Hopman et al., 2014; Richmond R.C. Other possible benefits that have been explored include: the fitness advantages of hair color (Adhikari et al., 2016; Hysi et al., 2018), nasal shape and climate adaptation (Zaidi et al., 2017) and the benefits of darker skin pigmentation (Wilde et al., 2014; Aelion et al., 2016). doi: 10.1093/hmg/ddu150, Crouch, D. J. M., Winney, B., Koppen, W. P., Christmas, W. J., Hutnik, K., Day, T., et al. A previous orofacial cleft GWAS found no clear evidence for enrichment of tissue-specific signals, concluding that this may be attributable to a lack of suitable tissue types (Leslie et al., 2017). Another even smaller group of Irish people (around 1% of the population) have black hair, light or tan skin, and brown eyes.

Second, when testing causality, epigenetic modifications can vary across the life-course, so it can be difficult to discern the direction of effect between an epigenetic modification and the phenotype.

For this reason, ancestral markers are often included in facial prediction models (Claes et al., 2014; Ruiz-Linares et al., 2014; Lippert et al., 2017). Twin studies have historically been employed to explore the relative genetic and environment influence on facial shape exploiting the genetic differences between monozygotic and dizygotic twins (Visscher et al., 2008).
