Explain how we know that there are NO races, or biological subspecies, in modern humans. In your answer be sure to compare and contrast scientific concepts of race and socially constructed concepts of race. You must use at least 2 of the following terms in your essay Fst, cline, skin reflectance Refer to craniometric data, genetic data, or patterns of disease. And finally, give examples of why we continue to use simplistic racial categories for humanity when we know they are inaccurate.
Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
![### Understanding the Concept of Race in Modern Humans
**Question Prompt:**
Explain how we know that there are **NO races**, or biological subspecies, in modern humans.
**Instructions for Your Essay:**
1. **Comparison and Contrast**: In your answer, be sure to compare and contrast scientific concepts of race and socially constructed concepts of race.
2. **Essential Terms**: You must use **at least 2** of the following terms in your essay:
- Fst
- Cline
- Skin Reflectance
3. **Data References**: Refer to craniometric data, genetic data, or patterns of disease.
4. **Societal Implications**: And finally, give examples of why we continue to use simplistic racial categories for humanity when we know they are inaccurate.

### Additional Notes for Students:
- **Fst** measures genetic variation among populations, which has shown that the differences within populations are far greater than those between what were traditionally labeled as "races".
- **Cline** refers to the gradual change in certain characteristics (such as genetic traits) observed across a geographical area rather than distinct racial categories.
- **Skin Reflectance** studies reveal that the variation in skin color is continuous and influenced by environmental factors such as UV radiation, further disputing the existence of distinct biological races.
Utilize scientific data and socio-historical context to strengthen your argument. Consider how race as a social construct impacts various aspects of society, including systemic inequalities and individual identities.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd8318901-18c5-4ecf-a8b3-d62fb276c04d%2F480f888d-a2be-4ff9-bfa3-3bca32445beb%2Fde4l3n_processed.png&w=3840&q=75)
