It is the same # 8, you will solve genetics problems using Punnett squares
You include your completed Punnett squares to show how you arrived at your answers, and provide the answers to the questions, including probabilities of both genotypes and phenotypes, clearly labeled which is, you will get credit. Use the examples in Lessons 9B and 9C as your guide.
Problems to solve
1.What are the probabilities of blood genotypes and phenotypes for the offspring from a cross between a mother with IAIA blood and a father with IBi blood?
2.Hemophiliacs have blood that does not coagulate well, and they often die at a young age. The disease allele is recessive and X-linked. The normal allele (N) is completely dominant over the disease allele (n). If a hemophiliac woman and a non-hemophiliac (normal) man have children, what percentage of their sons would be expected to have the disease? What percentage of their daughters would be expected to have the disease?
3.If a woman who is heterozygous for the hemophilia trait and a hemophiliac man have children, what percentage of their sons would be expected to have the disease? What percentage of their daughters would be expected to have the disease?
