GenotypeA/− ; C/− ; R/− is colored; all others are colorless.A colored plant is crossed with three tester plants ofknown genotype. With tester a/a ; c/c ; R/R, the coloredplant produces 50 percent colored seeds; with a/a ;C/C ; r/r, it produces 25 percent colored; and withA/A ; c/c ; r/r, it produces 50 percent colored.

1 pts The pedigree below shows the expression of Huntington's disease in a family. Huntington's disease is a fatal genetic disorder that causes the progressive breakdown of nerve cells in the brain. It deteriorates a person's physical and mental abilities usually during their prime working years and has no cure. Huntington's is inherited as a dominant allele (H). Examine the pedigree below and determine the genotype for individual "2" DODO0O 2. O HH O Hh О h O either HH or Hh
Pea PlantsIn pea plants, a round-seed shape (R) is dominant over a wrinkled-seed shape (r). A round-seeded pea plant was crossed with another round-seeded pea plant. What are the genotype(s) and phenotype(s) ratios of the F1 generation? Show all possibilities using Punnett squares. State the F1 generation genotypes and phenotypes.
In peas, the yellow allele is dominant over the green allele. A plant with yellow peas was crossed to a plant with green peas. The resulting plants were 50% yellow and 50% green. What is the genotype of the parents in this cross? G/g xg/g OG/G x G/g G/Gxg/g Og/g *g/g OG/g x G/g
1 Name Non-Mendelian Genetics Part 1: Incomplete Dominance In radishes, the gene that controls color exhibits incomplete dominance. Pure-breeding red radishes (RR) crossed with pure- breeding white radishes (rr) make purple radishes. What are the genotypic and phenotypic ratios when you cross a purple radish with a white radish? Genotype Probabilities: Phenotype Probabilities: Crosses between a yellow rat and a yellow rat always produce yellow rats (YY). Crosses between a white rat and a white rat always produce white rats (yy). But crosses of a white with a yellow produce a cream rat. What are the genotype and phenotype ratios if you cross two creams? Genotype Probabilities: Phenotype Probabilities: Part 2: Co-dominance In chickens, Black feathers (B) are co-dominant with White feathers (W). The hybrid is checkered. Cross a checkered chicken with a black chicken to determine the possible phenotypes for the baby chicks. Possible phenotypes: In cattle, red fur (R) is co-dominant with…
