Red flowers (allele CR) are incompletely dominant over white flowers (allele CW), resulting in three possible phenotypes: red, pink, and white flowers. Both parents express pink flowers. a. What is the genotype of the parents? and
b. What is the gametes coming from both the parents?
c. What is the probability of having pink flower in the offspring?
d. What is the probability of having white flower in the offspring?

Factors that can increase mutation rates a. high temps b. low temps c. food additives d. uv rays

What was the purpose of mendel's experiments with dihybrid crosses? a. to determine if dna was a transforming factor b. to determine if traits could be recessive c. to determine if traits affected each other d. to determine if traits had more than one allele

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
