4. Mr. Salazar has Type A blood while Mrs. Salazar has Type B. They have four children. Bobbie has Type A, Gabbie has Type B, Alex has Type AB, and Teddie has Type O. What are the genotypes of all six people in this family? NOTE: The ABO blood type gene has three alleles. IA and IB are codominant; i (for Type O) is recessive to both.

6. Alice has type A blood and her husband Mark has type B blood. Their first child, Amanda, has type O blood. Their second child, Alex, has type AB blood. What is Alice's genotype? What is Mark's genotype?_ Show how you found the answer by completing the Punnett square(s) below: 7. Candace has type B blood. Her husband Dan has type AB blood. Is it possible for Candace and Dan to have a child that has O blood? Explain why or why not (use a Punnett square to help). 8. Ralph has type B blood and his wife Rachel has type A blood. They are very shocked to hear that their baby has type O blood, and think that a switch might have been made at the hospital. Can this baby be theirs? Explain why or why not (use a Punnett square to help).
Cystic Fibrosis (CF) is an autosomal recessive condition. Therefore, heterozygous (Cc) carriers do not display symptoms. Two parents who are carriers plan to start a family and you are a genetic counselor helping to advise them about their chances of having children affected by CF. a) Suppose the couple has 4 children, each one year apart. What is the probability that all 4 children will inherit CF? b) What is the probability that any 3 of their 4 children will not inherit CF, but 1 will be affected? c) What is the probability that their first child will not inherit CF, but the younger 3 children will inherit CF?
A young couple went to see a genetic counselor because each had a sibling with cystic fibrosis. (Cystic fibrosis is a recessive disease, and neither member of the couple nor any of their four parents is affected.) What is the probability that the female of this couple is a carrier? What are the chances that their child will have cystic fibrosis? 3. What is the probability that their child will be a carrier of the cystic fibrosis disease allele?
Red-green color blindness is inherited through an X-linked, recessive allele (b). Two parents, Fred and Ginger, have normal vision. They have two daughters, Takiyah and Kelly, who also have normal vision, and a color-blind son, David. 3. Daughter Kelly has a color-blind son, Kevin. Daughter Takiyah has five sons, all with normal vision. What are the genotypes of all the individuals? Show all your work! Fred Ginger David Takiyah Kelly Kevin Takiyah's five sons If Kelly marries a man with normal vision, what is the probability that she'll have a color-blind son? a color-blind daughter?
2) You're the director of Foothill Presbyterian Hospital's maternity ward, and you have four mixed-up babies, with blood types of O, A, B, and AB. The four sets of desperate parents are threatening to sue you if you don't get their babies back. You know the blood types (phenotypes) of the parents are: i) AB and O ii) A and O iii) A and AB iv) O and O You also know that each set of parents has only one child (no sets of twins, that is). Match each baby with its parents.
YOUR SISTER DIED FROM TAY-SACHS DISEASE, INHERITED AS A RECESSIVE ALLELE (t). you're married and planning to start your family. you're worried about the disease and decide to have genetic testing to see if you or your spouse is a carrier of the tay-sachs allele. the test results show that you're a carrier of the allele, but your spouse isn't. what is the probability that you and your spouse will have a child with tay-sachs disease? show your work.
1. Mary and Joe are both healthy individuals. Joe has a mother who suffered from cystic fibrosis, an autosomal recessive disorder. Mary has been genetically tested in order to find out if she has the allele responsible for this disease and her tests came out positive. They are planning on having two children together in the near future. What is the probability that she and Joe will have either 2 boys who have the disorder, OR that they have one boy who has the disorder and one boy who does not? (in other words, what is the probability that any of these two outcomes takes place? a) 1/8 b) 1/16 c) 3/32 d) 1/64 e) 9/64

1. In humans, hemophilia is a sex linked trait. Females can be normal, carriers, or have the disease. Males will have the disease or not (but they won't be ever carriers) XH XH = female, normal XH Xh = female, carrier Xh Xh = female, hemophilic XH Y = male, normal Xh Y = male, hemophilic a) Show the cross of a man who has hemophilia with a woman who is a carrier. b) What is the probability that their children have the disease

Additional problems (Chapter 4 (Extension of Mendelian Inheritance): 1. In rabbits, coloration of the fur depends on alleles of the gene c. From information given in the chapter, what phenotypes and proportions would be expected from the following crosses: a) CC X cc b) Cc x Cc c) Cc x Ccch d) cc x cc 2. From the information given in the chapter about the ABO blood types, what phenotypes and ratios are expected from the following matings: a) type AB x type O b) Type AB x type B individual whose mother is type O c) Type O x Type A individual whose father is type O d) Type Ox type O 3. A woman with type AB blood type gave birth to a baby with type B blood. Two different men claim to be the father. One has type A blood and the other type B blood. Can the genetic evidence decide in favor of either? 4. You have been studying a trait that seems to be present in every generation within a particular family. Further, you have observed that every affected offspring has at least affected parent…
Part B 1. For the remaining characteristics, you will be looking at homozygous and heterozygous traits. Each trait will be determined to be homozygous recessive, homozygous dominant, or hetero- zygous. Letters representing the alleles will be given to you; the uppercase letter is always dominant and the lowercase letter is always recessive. If both dice rolled are even numbers, it indicates homozygous dominant alleles; if both are odd, it indicates homozygous recessive alleles; if one is odd and the other even, it indicates heterozygous alleles. 2. Eyebrows: Use the alleles "A" and "a" for this trait. Two separate brows are the dominant trait, whereas the unibrow (or one continuous brow) is recessive. 3. Eye shape: Use the alleles "R" and "r" for this trait. Round eyes are the dominant trait; almond shaped eyes are recessive. 4. Hitchhiker's thumb: Use the alleles "H" and "h" for this trait. Straight thumbs are dominant; Hitchhiker's thumbs (the curving upward of the thumb) are…
