Mr. and Mrs. Flynn are concerned because their new baby doesn't resemble either of them and has type O blood. Mr. Flynn is type A and Mrs. Flynn is type B. They're sure that it's impossible to have a baby with a different blood type than the parents, and so they conclude that a mistake has been made. Are they correct? Explain your answer. Be specific. Use the correct blood alleles (IA, IB, i) in your explanation.   genotypes:   Mr. Flynn _________         Mrs. Flynn __________           their baby ___________

Mrs. Kaur and Mrs. Sharma had babies on the same day at the same hospital. Mrs. Kaur took home a girl (Harleen) and Mrs. Sharma received a boy (Baldeep). However, Mrs. Sharma was sure she had given birth to a girl and brought a suit against the hospital. Blood tests showed that Mr. Sharma was type O. Mrs. Sharma was type AB and Mr. & Mrs. Kaur were both type B. Harleen was type O and Baldeep was type A. Had a mistake occurred? Did the parents bring home the incorrect babies? a. What is Mr.sharma genotype b. What is Mrs.sharma genotype c. What is Mrs. Kaur genotype Has a switch occurred? Why or why not?

Hemophilia, disease in which the blood lacks a clotting factor, is caused by an X linked recessive gene. Joe doe not have hemophilia and Lucille is heterozygous for the condition.  What is the chance that their MALE child will have hemophilia? (Note: you are calculating the probability for their MALE children only, in other words if they have 1 male child, what is the probability that he will be born with the disease?)     0%     1/4 or 25%     2/4 or 50%     3/4 or 75%     4/4 or 100%

Alex is newly pregnant with twins and curious about everything about her developing children. Her doctor was able to tell her that her twins are dizygotic twins via ultrasound. In your essay, describe the difference between monozygotic and dizygotic twins and explain how each is conceived. Alex is also wondering about the genetics of her children and how they will act when they are older. Offer an explanation of genotype and phenotype and provide an example of each specific to Alex’s future children being dizygotic twins. Finally, in your previous explanation be sure to also describe how most traits are both polygenic and multifactorial and how that may influence her twins’ phenotypes.

Draw the punnet square and explain the results

A female with genotype IBi has a child that has blood type O (genotype ii). Which of the following genotypes could the child's father have? Select all correct answers.   ii IAIB IAi IBIB

If a man with type O blood has a child with a woman who is heterozygous for type B blood, what are the possible blood types for this child?

Duchenne’s muscular dystrophy (DMD) is an X-linked disease that causes progressive muscle weakness and is often fatal. “XD” represents the wild type allele, and “Xd,” the mutant allele. Jonah is XDXd Y and his brother Pete is Xd Y. Jonah and Pete BOTH have DMD of equal severity and phenotypes. You might have thought Jonah’s DMD would be less severe given his genotype. To better understand the situation, you investigate Jonah’s Xist chromosome region in his defective muscle cells. Which of the following is consistent with his phenotype? (Select all that apply.) The Xd-containing chromosome is inactive in defective muscle cells. The XD-containing chromosome has a methylated Xist promoter. The XD-containing chromosome has an unmethylated Xist promoter. The Xd-containing chromosome is active in defective muscle cells.

Can you please not type the answer can you write it on a paper

A couple finds out that both the male and the female are heterozygotes (carriers) for Tay Sachs. Draw a punnet square for this couple. What is the likelihood that this couple will have an offspring with Tay Sachs?
