Suppose that tomatoes with the RR genotype are red and those with rr are yellow. Assuming that this reflects conventional genetics shorthand of uppercase and lowercase letters, which of the following is true?

The specific name of the 5-carbon sugar that is found in DNA is _______.  This 5-carbon sugar is a ________.

(1 point).   In rabbits, phenotype A (white fur and long ears) is caused by dominant alleles for both white fur (F) and long ears (G); phenotype B (black fur and short ears) is caused by recessive alleles for both black fur (f) and short ears (g). In the parental generation, a rabbit that is homozygous dominant for both traits of phenotype A is mated to a rabbit that is homozygous recessive for both traits of phenotype B. 1. What is the genotype AND phenotype of the parents? 2. What is the genotype AND phenotype of the F1 generation? 3. If you cross an F1 with an F1 and complete the 4×4 Punnett square: What genotype would you find in the upper left corner of the Punnett square? What genotype would you find in the lower right corner of the Punnett square? 4.  In the F2 generation, what is the expected ratio of phenotypes listed below, given the following possible phenotypes?        Phenotype A:  white fur and log ears        Phenotype B:  black fur and short ears        Phenotype C:  white fur and short ears        Phenotype D:  black fur and long ears a. 1A:1B b. 1A:0B c. 3A:1B d. 9A:3C:3D:1B e. 9B:3C:3D:1A

Green and yellow are two alleles of the same gene for stripe color. Suppose members of a homozygous strain of salamanders with yellow stripes are crossed with a homozygous strain with green stripes. The resulting offspring have both yellow stripes and green stripes.  Which dominance pattern is most consistent with the observations?
