These transcriptional factors may be limited to detail the precise facial shape or can be quickly activated in rapid periods of growth and development. It is important to identify early life exposures (particularly conception to birth) that may influence later life health outcomes. These landmarks are defined by identifiable/describable facial features, e.g., nasion, inner/outer canthi, commissures that can generate Euclidean distances, angles, and ratios (Farkas et al., 2002, 2004, 2005). 9, 255266.

You also have the ginger/red hair colour that is quite common on the british isles, most common in Ireland and Scotland, I believe. Specific facial features which were taken into account by the software included nose width and length, lip thickness and hairline. Understanding the face will explain why we look the way we do a range of normality and abnormality that will be useful in healthcare applications and forensic science. It has been hypothesized that deleterious coding variants may directly cause congenital anomalies while non-coding variants in the same genes influence normal-range facial variation via gene expression pathways (Shaffer et al., 2017; Freund et al., 2018). Detection and interpretation of shared genetic influences on 42 human traits. Dixon, M. J., Marazita, M. L., Beaty, T. H., and Murray, J. C. (2011). Prevention may be challenging (other than continually improving environmental conditions and reducing exposure to potential epigenetic factors) as facial development occurs very early in gestation during a period whereby the mother is often unaware she is pregnant.

However, large-scale population studies are needed to identify more genetic variants not only in the context of facial shape but general body development with particularly attention to puberty.
