I have 4 questions for anthropology That needs to be answered

1. DNA is responsible for your phenotype, but to what extent? How much, if at all, do environmental factors play a role? Can you find examples (remember keep your sources academic)?

2. Define polygenic and pleiotropic traits and explain their significance for researchers’ efforts to link human genotypes to phenotypes.

3. Use what you know about meiosis to explain Mendel’s law of segregation and law of independent assortment.

4. Should genes be patented? Why or why not?
