5. Rather than studying you are watching Maury. A couple comes on with a baby. The father has brown eyes, his parents, grandparents, sister, and brothers all have brown eyes. The mother has blue eyes and the baby has blue eyes. The brown eye allele is dominant to blue eye allele. Using this information, answer the following questions. What is the likely genotype of the father? What is the genotype of the mother? What is the genotype of the child?

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 4 |IL 1 I Section 5: Trihybrid cross and Laws of probability For a trihybrid cross, in which inheritance of alleles for three genes is tracked, drawing a Punnett square that combines all three genes may not be practical. Instead the laws of probability may be used. The product law of probabilities says that when alleles for separate genes segregate independently, we can figure out the probability of a particular combined genotype by multiplying the probability of the alleles for each gene. 13. We cross a homozygous tall pea plant with yellow, round seeds to a homozygous dwarf pea plant with green, wrinkled seeds. All the F1 offspring are all tall plants with yellow, round seeds. a. What are the expected F2 ratios (use fractions) of tall and dwarf plants? b. What are the expected F2 ratios (use fractions) of yellow and green seeds? C. What are the expected F2 ratios (use fractions) of round and wrinkled seeds? d. What are the possible F2 combined phenotypes and their expected ratios…
Brown eyes are dominant over blue. This is NOTA sex-linked trait. If a blue-eyed colorblind woman marries a normal visioned man who is homozygous for brown eye color, what kind of children might they expect with respect to these two traits? 5. Genotype of woman _Genotype of man What two genotypes are possible in the children? If one of the sons in turn marries a heterozygous brown-eyed, normal visioned woman, not a carrier, what kinds of children might they expect? Genotypes Phenotypes
10. If B=brown eyes and b=blue eyes, and a man with brown eyes and a woman with blue eyes have a child with blue eyes, what is the genotype of the man for eye color? Assume complete dominance. * BB ВB or Bb Bb brown can't tell without more information
Hemophilia is inherited exactly like colorblindness. The dominant allele calls for normal clotting time of the blood. The recessive allele calls for hemophilia. A normal woman marries a normal man. They have one daughter and 14 sons, all normal. In view of this, what allele combination would this woman most likely have? Why do you say this? What is the probable genotype of the daughter? 7.

D Page view A Read aloud Draw Highlight PRA Can you curl your tongue up on the sides? Tongue-curling in humans is a dominant genetic trait. Suppose a man who is Tt for tongue-curling marries a woman who is also Tt for this trait. What are the possible genotypes and phenotypes of their children and the percent chance for each? 4. 1 Fill in the table: Genotype Phenotype Chance
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?
5. A woman who is a carrier for colorblindness marries a colorblind man. The woman nas 5 nngers on each hand and the man, whose father had father had 5 fingers, has 6 fingers. (Polydactyly-have 6 fingers on each hand-is inherited as an autosomal dominant trait. What percent of their children do you expect to be colorblind with 5 fingers? man with type AB blood is married to a woman with type O blood. They have 2 natural children 01one adopted child. 'One child has type A blood, one has type B blood and the other has type O blood. Whi s adopted?
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.
What percentage of all children will be carriers? What is the sex of the carriers? 2. A heterozygous woman carrying the recessive gene for hemophilia marries a man who is not a hemophiliac. Assume the dominant gene is X" and the recessive gene is X". The woman's genotype is X"X", and her husband's genotype is X"Y. What is the potential percentage and sex of their offspring who will be hemophiliacs? % males; % females 100 What percentage can be expected to lack the allele for hemophilia? What is the anticipated sex and percentage of individuals who will be carriers for hemophilia? 2014 sex %,
