EXERCISE 2 SKIN COLOR ACTIVITY 2 Work with a small group or alone to complete this exercise Recent research has identified a gene (SLC45A2) that codes for a protein that impacts melanin production in humans and other animals. There is a mutation in this gene called L374F with two allele variations. The L374 allele correlates with darker pigmentation, and the F374 allele correlates with lighter pigmentation. Researchers collected DNA samples from people in 14 European, Asian, and African populations and identified the frequency of the F374 allele in these groups. Review the data in the chart and answer the questions that follow

Explanation / Answer

Excercise 2:

1. Highest French ( France) 98

2. Lowest Han (China) 119

3. No. It could be mixed population of different regions living in those areas. So we cannot.

4. As the hint says may be due to evolution, climatic conditions and geographic location the allele is missing in Japanese population.

All the best!
