4.) A man and a woman have a child. The father is blood type A, and one of his parents was blood type A and the other was blood type O. The mother is blood type B, and one of her parents was blood type B, the other type O. Both the father and the mother are carriers of the Bombay allele. (Neither of the type-O grandparents were type O because of the Bombay allele – they had the regular type O genotype.) WhataretheoddsthattheirbabywillhavebloodtypeO? WhataretheoddsthattheirbabywillhavebloodtypeAB? (Hint – for this question, you should draw out a pedigree and fill in as much as you can for the genotypes of BOTH genes that are involved.)
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.
7. The ability to roll your tongue (R) is dominant to lack of this ability (r). A. What is the genotype of a man who can roll his tongue if his father couldn’t? B. If a man who is heterozygous for tongue rolling marries a woman who is heterozygous, what would you predict for the genotypes and phenotypes of their children?
2. Be able to compare and contrast (discuss similarities and differences in) in your own words the terms genotype and phenotype, wild-type and mutant phenotypes. Step by step.
1. A mother with blood type A has a child with blood type O, and she claims that Mister X is the father. Mister X denies that he could possibly be the father, because he has blood type B. If you were the judge presiding over this case, which of the following arguments would you find most convincing? a. Mr. X could be the father if his blood genotype is IBIB, and the mother’s blood genotype is IAIA b. Mr. X cannot be the father because a child with blood type O cannot have a parent with blood type B c. Mr. X could be the father if his blood genotype is IBi, and the mother’s blood genotype is IAi d. Mr. X cannot be the father because a parent with blood type B cannot have a child with blood type O e. Mr. X cannot be the father because the human ABO blood types are sex-linked traits 2. A monohybrid cross between two pea plants producing yellow peas, resulting in an F1 phenotypic ratio of 3:1 (three yellow pea plants to one green pea plant) indicates what about the parental pea plants?…
2.In dogs, there is a hereditary deafness caused by a recessive allele, d. A kennel owner has a male dog that she wants to use for breeding purposes if possible. The dog can hear, but the owner is unsure of the genotype. She does a testcross (crosses it to a homozygous recessive dog), and two of the five offspring are deaf. This means that the male dog A.has the genotype DD B.has the genotype Dd C.is still of unknown genotype since there were offspring of both deaf and hearing phenotypes. D.has the genotype dd
1.Which among the following statements is INCORRECT? A.Phenotype is the pair of genes that carries the genetic makeup of an organism B.Homozygous is a combination of two dominant or two recessive allele C.A recessive allele must be received from both parents to bring about a recessive phenotype D.Heterozygous is a combination of one dominant allele and one recessive allele
3. A student states, “If a person expresses the dominant trait for eye color, then the person’s genotype must be BB.” Is the student correct? Explain why or why not. Assume that the B allele is dominant, and the b allele is recessive.)
1. A woman is colorblind. Construct a Punnett square and using versions of the letter “C” determine if she marries a man with normal vision: What are the chances her sons will be colorblind? What are the chances her daughters will be colorblind? What are the chances of having a carrier daughter? 2. Both the husband and wife have normal vision. Their son is colorblind. What can you conclude about the father’s genotype? What about the mother’s genotype? Father: Mother: 3. If a young girl has fragile X syndrome, a recessive trait (f), what is her genotype? What are the possible genotypes of her father and mother? Mother: _________ or __________ Father: _________________ If her brother also developed this condition, which parent (father, mother, or both) contributed a disease allele? Explain your answer as well as constructing Punnett squares to support your answer. 4. Both the mother and father of a hemophiliac son have normal blood clotting. What are the genotypes of the…

3) The ability to curl ones’ tongue up on the sides (T) is dominant to not being able to roll your tongue (t). a. A woman who can roll her tongue marries a man who cannot. The first child has the same phenotype as the father, what are the genotypes of the mother, father, and this child? b. What is the probability that the second child won’t be able to roll it’s tongue?
