2. In a strain of chickens, there are birds with white, black, or blue feathers. In crosses between ten white hens and ten blue roosters, there are 100 offspring: 24 hens with blue feathers, 26 roosters with blue feathers, 23 hens with white feathers, 27 roosters with white feathers. When crossing blue hens and white roosters, there are 100 offspring: 25 hens with blue feathers, 25 roosters with blue feathers, 26 hens with white feathers, 24 roosters with white feathers. A. Using allele symbols, create a plausible explanation for these traits. Why is this trait not sex-linked? When crossing ten black roosters and ten white hens, you observe 100 offspring: 51 hens with blue feathers, 49 roosters with blue feathers. When crossing white roosters and black hens, you observe 100 offspring: 50 hens with blue feathers, 50 roosters with blue feathers B. Use allele symbols to create a plausible explanation for these traits. C. Using evidence of all crosses, what would you predict if you…

How many different offspring genotypes are expected in a trihybrid cross between parents heterozygous for all three traits when the traits behave in a dominant and recessive pattern? How many phenotypes? 64 genotypes: 16 phenotypes 16 genotypes; 64 phenotypes 8 genotypes; 27 phenotypes 27 genotypes; 8 phenotypes
What genotypes, and in what frequencies, will be present in the offspring from the following matings? a. AABBaaBB b. AaBbaabb c. AaBBAABb d. AaBbAaBb
Use the probability method to calculate the genotypes and genotypic proportions of a cross between AABBCc and Aabbcc parents.
Several alleles affect traits of roses, such as plant form and bud shape. Alleles of one gene govern whether a plant will be a climber (dominant) or shrubby (recessive). All F1 offspring from a cross between a true-breeding climber and a shrubby plant are climbers. If an F1 plant is crossed with a shrubby plant, about 50 percent of the offspring will be shrubby; 50 percent will be climbers. Using symbols A and a for the dominant and recessive alleles, make a Punnett- square diagram of the expected genotypes and phenotypes the cross between the F1 offspring and the shrubby plant.
In sweet pea plants, an allele for purple flowers. (P) is dominanl when paired with a recessive allele for red flowers (p). An allele for Jang pollen grains (L) is dominant when paired with a recessive allele for round pollen grains (L). Bateson and Punnett crossed a plant having purple flowers and long pollen grains with one having white flowers and round pollen grains. All F1 offspring have purple flowers and long pollen grains. Among the F2 generation, the researchers observed the following phenotypes: 296 purple flowers/long pollen grains 19 purple /lower/ round pollen grains 27 red flowers/long pollen grains 85 red flowers/round pollen grains What is the best explanation for these results?
8. In dihybrid crosses of heterozygous parents, the ratio 9:3:3:1 indicates ___. a. codominance c. incomplete dominance b. independent assortment d. three alleles for each trait For the next four questions, use the following key: a = All the offspring will exhibit the dominant trait. c = The recessive trait will show up in about 50% of the offspring. b = All the offspring will exhibit the recessive trait. d = The dominant trait will show up in about 75% of the offspring. What will be the result if: 9. Bb mates with bb? 10. BB mates with bb?
