DNA as a Genetic Template

DNA as a Genetic Template

Two structural features of the DNA molecule provide a basis for the mechanisms of heredity: the four nucleotide bases and its double-stranded nature. The Watson-Crick model of double-helical DNA structure, proposed in 1952, drew heavily upon the X-ray crystallography work of researchers Rosalind Franklin and Maurice Wilkins. Watson, Crick, and Wilkins jointly received the Nobel Prize in Physiology or Medicine for their work in 1962. Franklin was, controversially, excluded from the prize for...

The DNA Helix

The DNA Helix

Deoxyribonucleic acid, or DNA, is the genetic material responsible for passing traits from generation to generation in all organisms and most viruses. DNA is composed of two strands of nucleotides that wind around each other to form a spring-like structure called a double helix. However, the double helix is not perfectly symmetrical. Instead, there are regularly occurring grooves in the structure. The major groove occurs where the sugar-phosphate backbones are relatively far apart. This space...

Muscles for Facial Expressions

Muscles for Facial Expressions

The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

Facial Feedback Hypothesis

Facial Feedback Hypothesis

Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Background:

Human facial diversity is significant but poorly understood.
Previous studies have not fully explained the genetic underpinnings of facial variation.

Purpose of the Study:

To investigate the relationships between facial shape, sex, genomic ancestry, and craniofacial candidate genes.
To develop a novel method for identifying genes that influence normal-range facial features.

Main Methods:

Utilized spatially dense quasi-landmarks to measure face shape in populations with mixed West African and European ancestry.
Employed bootstrapped response-based imputation modeling (BRIM) to analyze facial variation.
Jointly modeled sex, genomic ancestry, and genotype to identify independent allelic effects on facial features.

Main Results:

Identified significant effects of sex, genomic ancestry, and specific genes on facial features.
Validated response-based imputed predictor (RIP) variables using self-reported and observer-based data.
Demonstrated the ability to approximate facial appearance from genetic markers.

Conclusions:

The BRIM approach is a novel method for identifying genes affecting normal-range facial features.
This study provides insights into the genetic architecture of human facial diversity.
The findings support the potential for predicting facial appearance from genetic data.
