Traits of Race

Traits of Race

Racial traits encompass a wide range of physical, behavioural and physiological characteristics specific to different racial groups. Two aspects distinguish people based on phenotypic and genotypic traits.

1. Phenotypic Traits: These are the observable physical characteristics that distinguish one race from another. They include:

i. Skin Color: Varying from light reddish white to olive brown, brown to black, and light yellow to yellow brown, skin colour is a significant trait in racial classification.

ii. Hair Form: The shape, colour, texture, and abundance of hair are considered. For example, straight hair in Mongoloid races and curly or woolly hair in Negroid races.

iii. Eye Form: The shape, colour, and presence of folds in the eyelids are noted in racial classification.

iv. Nose Form: The shape and structure of the nose, including the nasal bridge and depression, are used to distinguish racial groups.

v. Stature: Individual height is also a factor, with some races characterized as tall or short.

vi. Head Form: Another distinguishing feature is the shape of the head, whether brachycephalic (short and wide) or dolichocephalic (long and narrow).

vii. Anthropometric Measurements: Various body measurements such as bizygomatic breadth, limb proportions, and chest and thigh circumference are used in classification.

2. Genotypic Traits: These are genetic characteristics that are inherited and not modified by environmental factors. They include:

i. Blood Groups: ABO, Rh, and other blood group systems vary in frequency among different populations and are used as genetic markers.

ii. Dermatoglyphics: The study of skin ridge patterns on fingers, palms, toes, and soles, which are inherited independently and remain unchanged by the environment.

iii. Hemoglobin Variants: Different forms of haemoglobin, such as sickle cell haemoglobin, are used in racial classification.

iv. Some other variants: The ability to taste phenyl thiocarbamide, colour blindness, sweat glands, etc., are used for racial classification.

v. DNA fingerprints: DNA fingerprinting can help evaluate racial classification properly. The genomes of various populations may be used for this purpose.

The traits of race are a combination of physical characteristics and genetic markers that have been used historically to classify human populations. However, it also highlights the limitations and controversies surrounding the concept of race, advocating for a more unified understanding of human diversity.
