Problem 26 in your text involves incomplete dominance; we know this because the phenotype of the heterozygote is in between (and different from) the phenotypes of the homozygotes. If you had a prized palomino horse and wanted to maximize the chance that the foal was also palomino, would you cross your palomino horse with a chestnut, a cremello, or another palomino horse? Justify your answer with expected genotype and phenotype ratios for the various crosses.

In this inquiry, you will investigate a variation of the assumption that there are only two alleles per gene. In this exercise, you will cross a purebred horizontally-striped fly with a pure bred vertically-striped fly. F1 results are: F1 Observed Results: 1000 black F1 flies Question #1: Describe the genotypes of the parents? Question #2: Describe the genotype of the F1 offspring. Question #3: What pattern of inheritance seems to be operating here? Now you will cross 2 flies, one...
8. Pea plant breeders wanted to pick healthy tall plants that were homozygous for the height gene. They had a collection of 10 plants that were healthy and tall, but the genotypes were unknown. How might they determine if the 10 tall plants were heterozygous or homozygous for the height gene? a. What genotypes are possible for tall pea plants? b. What cross would be most useful in distinguishing between homozygous and heterozygous tall plants? c. Explain the concept of...
6. In tigers, a dominant allele (W) is responsible for the expression of the normal orange pigment. Individuals that inherit twe recessive alleles (w) lack the normal orange pigment in their fur, appearing white with black stripes. A pair of normally colored parewis produces a cub that is white with black stripes and scab that is orange with black stripes. What are the possible genotypes of the cube? b. What are the possible genotypes of the parents? 6. Explain your...
Circle the correct answer, there may be more than one correct answer 1. Diploid Organisms: a) typically have 23 pairs of chromosomes b) are heterozygous for a trait when they carry different alleles c) carry 2 copies of chromosomes d) are homozygous for a trait when they carry different alleles 2. Why are garden peas a good subject for Mendel's experiments? a) garden peas had either or traits b) garden pess could self-pollinate to produce offspring of the same variety...
