56. What is incomplete dominance? What is the probability of getting “ heads ” in a coin toss? Explain the relationship between traits and heredity. Explain the difference between dominant and recessive traits. Describe how probability can describe possible outcomes in offspring. How would the importance of Mendel ’ s experiments have been different if he had never done the second experiments? What are the possible phenotypes for plant height in Mendel ’ s experiments? Since sex cells only have half the chromosome cells that are found in a regular cell, how do they grow into cells that have a full set of chromosomes?
