8.Using Punnett squares, phenotypes, and genotypes, show me the difference between incomplete dominance and codominance. 10. From your textbook, you learned about sex-linked traits using Drosophilia eye color. For this question, we are going to look into sex-linked traits in humans. Color blindness is more often seen in males than in females. Using a Punnett square, demonstrate how this observation is supported using the concepts we’ve been practicing in this assignment.
