Since Scotland appeared in only one of the names, some people wondered what had happened to their Scottish ancestry. Eur. genome-wide association and longitudinal analyses reveal genetic loci linking pubertal height growth, pubertal timing and childhood adiposity. Scientists have merged dozens of famous faces to create what they call the most beautiful faces in the world. Decoding lamarck-transgenerational control of metabolism by noncoding RNAs. Indeed, the last Habsburg King of Spain, Charles II, was reported to have had difficulties eating and speaking because of facial deformities. J. Med. (2017). There are many imaging systems available to capture the external facial surface topography such as photography, lasers, photogrammetry, magnetic resonance Imaging (MRI), computerized tomography (CT), and cone beam computerized tomography (CBCT). 32, 122. on the growth of the face, for example, remodeling of the facial skeleton, spatial changes of the constituent parts of the facial skeleton through sutures, condylar and nasal cartilages as well as the soft tissues, neural and vascular networks. 15, 288298. Dis. (2017). 47, 12361241. The role of sonic hedgehog in normal and abnormal craniofacial morphogenesis. One or more facial landmarks can be used to generate principal components, geodesic distances, geodesic arrays, facial shells and signatures which can categorize patterns in facial features (Hammond and Suttie, 2012; Hallgrimsson et al., 2015; Tsagkrasoulis et al., 2017; Abbas et al., 2018). The GWAS studies have provided insights into the genetic influences on facial shape. Another mechanism via which environmental influences can affect facial traits is natural selection, where certain facial traits may have beneficial effects on reproductive fitness. Richmond, S. A., Ali, A. M., Beldi, L., Chong, Y. T., Cronin, A., Djordjevic, J., et al. 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). doi: 10.1006/jhev.2000.0403, Jablonski, N.

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). There is evidence to suggest that the effects of some of these substances can also continue post-natally through breast milk fed to the new-born (heavy metals Caserta et al., 2013; Dioxin Rivezzi et al., 2013). The genome is comprised of 3.2 billion nucleotides wrapped in octomeric units of histones (chromatin). Genome-wide association studies (GWAS) have investigated the association between normal facial variation and millions of single nucleotide polymorphisms (SNPs). Indeed, a previous study demonstrated that a major risk locus for non-syndromic cleft lip/palate (nsCL/P), in a non-coding interval, is involved in the regulation of gene expression in the developing murine face (Uslu et al., 2014) while another study found some evidence that nsCL/P genetic variants may influence nsCL/P risk via changes in DNA methylation and gene expression (Howe et al., 2018b).

In addition, there is evidence of pleiotropy, quantitative phenotypes and Mendelian traits all influencing multiple phenotypes suggesting a large number of loci contribute additively to facial variation.

The developing fetus may be subject to adverse environments at home, in the workplace or through lifestyle activities (smoking, alcohol and drug intake, allergens, paint, pest/weed control, heavy metals, cleaning, body products such as perfumes and creams). In addition, it is likely that one or more genes influence the whole shape of the face as well as more localized facial regions (Claes et al., 2018). Recognition of distinctive facial and lip features such as grooves, nodules, lip demarcation lines has also been reported (Merks et al., 2003; Wilson et al., 2013). 1),S126S146.

Disruption in early embryological development can lead to wide-ranging effects from subtle neurologic and facial features, which includes asymmetry, to significant impact on facial shape as characterized by a CL/P or in anomalies observed in craniofacial syndromes.

Many of these techniques have been evaluated in terms of facial coverage, speed of capture, processing time, accuracy, validity and cost (Kovacs et al., 2007; Heike et al., 2010; Kuijpers et al., 2014; Tzou et al., 2014). The Scottish Accent Genetic and environmental contributions to facial morphological variation: a 3D population-based twin study. Investigating an imprinting-like phenomenon in humans: partners and opposite-sex parents have similar hair and eye colour. To quantify facial features, landmarks have been traditionally used, taken either directly from the face or derived from photographs or radiographs. It originated in the 1500's and is always performed to traditional Irish music. This association suggests that developmental processes relating to normal-variation in philtrum development are also etiologically relevant to nsCL/P, highlighting the shared genetic influences on normal-range facial variation and a cranio-facial anomaly (Howe et al., 2018a). (2007). J. Craniomaxillofac. Lancet 374, 17731785.

B. N. Sharman (London: BBC One, BBC), 2 minutes. One study effectively predicted eye color (85% for brown and 70% for blue), hair color (72% for brown, 63% for blonde, 58% for black, and 48% for red) and ancestry (56%); which are relatively low levels and individually could not be relied on for certain identifications but has greater potential when used collectively (Keating et al., 2013).

This has been proposed as a method to build a profile of facial features from a sample of DNA (Claes et al., 2014) but could also be used to determine previous health history or future health risks (Idemyor, 2014). The modifiable nature of epigenetic processes has led to much excitement that these processes may mediate the effect of environmental exposures. doi: 10.1016/S1470-2045(16)30054-7, Al Ali, A., Richmond, S., Popat, H., Playle, R., Pickles, T., Zhurov, A.
