20 points need which of the following experimental conditions ensured that mendel would get accurate results in his experiments on pea plants? a. all of the above b. he physically controlled the breeding of the plants. c. he used true-breeding, or "pure breed" plants. d. he observed only traits that had two forms, such as "tall" and "short". in a population, purple flowers are dominant over blue flowers. determine which statement below is not correct. a. purple flowers must be either pp or pp. b. purple flowers and blue flowers can both be homozygous. c. blue flowers must contain two recessive alleles. d. it is more of an advantage to the purple flower to be homozygous dominant. mendel concluded that sexually reproducing organisms contribute only one copy of each factor to each of their egg or sperm cells. this was the basis for his a. law of independent assortment, because the male copies of a trait must go to the sperm cells and the female copies to the eggs. b. law of independent assortment, because mendel was responsible for the pollination of each plant physically and that altered the genes in each sex cell. c. law of segregation, because the two forms of each trait must come together to create a blending of the two in each offspring. d. law of segregation, because individuals have two forms for each trait and they must separate during the formation of eggs and sperm. jesi and tom are doing a project on genetics, and are analyzing their traits. they are looking specifically at the trait for "dimples". jesi has dimples, and tom does not. look at the image, and decide which statement below regarding dimples is true. jesi: dd tom: dd a. tom has dimples. b. dimples are a recessive trait. c. dimples are a dominant trait. d. jesi is homozygous for dimples. after observing the f2 generation, what conclusion did mendel come to? a. the recessive trait reappeared about 25% of the time. b. the recessive trait had disappeared in the f2 offspring. c. there appeared to be a blending, or intermediate, of traits in the f2 generation. d. none of the above are correct.
