A man who has type AB blood and a woman who has type O blood could are having children. What are the possible blood types for children of the couple? Explain your answer and the probabilities with a Punnett Square.
A survey was taken to determine the blood types of children from marriages in which the wife had the blood group AB and the husband had blood type A but one of his parents is type O. The survey resulted in 250 type A, 90 type B, and 110 type AB children. Is the deviation from the expected significant?
Two parents learn they are each carriers for Cystic Fibrosis, each having the genotype (Aa). Using a punnett square, perform a genetic cross to determine the probability that their children will inherit two recessive alleles and have Cystic Fibrosis (aa). In your answer, explain the probability using either percentages (%) or odds out of 4 (1/4, 3/4, etc).
If a father with type O blood and a mother with AB blood have children,calculate the percentages of each genotype and phenotype of the offspring from the Punnett square.
A test was done to determine the biological father of a child. The child's blood type is A and the mother's is B. The first man has a blood type of O, while the second has a blood type of AB. Which among the two men could possibly be the biological father? Use a cross of various genotypes. Additional Questions: Construct a punnect square Offspring’s possible genotype?
