And (b) What would be the probability of producing a child with the maximum number of active alleles? Show your work. You can answer both at the same time by first solving gene by gene for part "a" and then below these place probabilities for each gene by gene cross for part "b".

In addition to the two genes in problem 4, assume you now study a third independently assorting gene that has the alleles C and c. For each of the following genotypes, indicate what types of gametes will be produced: a. AA BB CC b. Aa BB Cc c. Aa BB cc d. Aa Bb Cc
2. In four-o’clocks, the allele for red flowers is incompletely dominant to the allele for white flowers, soheterozygotes have pink flowers. What ratios offlower colors would you expect among the offspringof the following crosses: (a) pink × pink, (b) white ×pink, (c) red × red, (d) red × pink, (e) white × white,and (f) red × white? If you specifically wanted to produce pink flowers, which of these crosses would bemost efficient?
1. a) If you were at risk of a fatal disease such as Huntington’s disease and only the 95% accurate preliminary genetic test was available, would you take the test? After all, 95% of the time the test would tell you whether you would eventually get Huntington’s disease or whether you did not have to worry about getting this disease. b) The linkage distance between the DNA sequence used in the test and the actual Huntington’ disease locus was 5%. In a large sample of the Venezuelan family, what percentage of people would inherit the DNA sequence but not the Huntington’s allele (i.e. be a false positive test for Huntington’s)? What percentage of that large Venezuelan family would not inherit the DNA sequence but would inherit the Huntington’s allele (i.e., be a false negative test for Huntington’s)?

4. Marfan syndrome is a genetic trait caused by in a dominant allele. The trait causes a weakening of the aorta that can be fatal. A teenager whose mother has the syndrome (but whose maternal grandfather was not affected), and whose father was unaffected, is concerend that she may have the trait. a. What is the phenotype of each of her parents? Genotype? b. What is the chance that the teenager has Marfan syndrome?
4. An albino corn snake is crossed with a normal-coloredcorn snake. The offspring are all normal-colored.When these first-generation progeny snakes arecrossed among themselves, they produce 32 normalcolored snakes and 10 albino snakes.a. How do you know that only a single gene is responsible for the color differences between these snakes? b. Which of these phenotypes is controlled by thedominant allele?c. A normal-colored female snake is involved in atestcross. This cross produces 10 normal-coloredand 11 albino offspring. What are the genotypes ofthe parents and the offspring?
8. In guinea pigs, the allele for black fur (B) is dominant over the allele for white fur (b). Similarly, the allele for straight hair (H) is dominant over the allele for having rough hair (h). Pure breeding rough haired guinea pigs with black fur were crossed with pure breeding straight haired guinea pigs with white fur. a. State the genotype and the phenotype of the F1 individuals produced as a result of this cross.b. Two F1 offspring were mated together. Calculate the expected ratio of phenotypes in the F2 generation.c. Show the completed Punnett square below.
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?…
3.) Provide three reasons why did Mendel choose pea plants as an experimental model?
4) The round pea seed allele (R) is dominant, while the wrinkled pea seed allele (r) isrecessive. A heterozygous round-seeded pea plant is crossed with a wrinkle-seeded peaplant. Use a Punnett Square to solve the following: a. Determine the predicted genotype ratio of the offspring. b. Determine the predicted phenotype ratio of the offspring. c. If this cross produced 50 plants, how many plants would you predict would bewrinkle-seeded pea plants? please if punnet square needed write down the P G and F1 also thanks
