PLEASE HELP LOL To test the hypothesis that lectin exposure increases the rate of cell division, onion plants were exposed to lectin dissolved in water or water alone. After 4 days, the onion plants' root tips were cut into thin slices, placed on a microscope slide and stained with a dye that binds to DNA, making it appear blue. Since it can be hard to distinguish each phase of mitosis using this method (as you probably experienced in part 1) cells were classified as belng in interphase or mitosis. More than 200 cells were counted in 8 onion plants of the same variety and age, grown in the same temperature. All plants were supplied with the same amount of fertilizer and nutrients. 1. Identify the parts of the experiment described above.

In a hypothetical breed of dogs, coat color is controlled by two genes. there are six different coat colors in this breed: black, brown, cream, gray, silver, and tan. consider the following crosses. cross 1: black females from a lineage of all black dogs are crossed with brown males from a lineage of all brown dogs. f1 males and females are all black. when f1 are intercrossed, f2 males and females are black or brown. cross 2: black females from a lineage of all black dogs are crossed with tan males from a lineage where all males are tan and all females are cream. f1 males are black, f1 females are gray. when f1 are intercrossed, f2 males and females are black, brown, gray, or tan. cross 3: silver females from a lineage where all females are silver and all males are gray are crossed with brown males from a lineage of all brown dogs. f1 males and females are all gray. when f1 are intercrossed, f2 males are black, brown, gray, or tan, f2 females are cream, gray, silver, or tan. select the correct statements regarding the mode of inheritance of the coat color genes. a) both genes are x-linked. b) both genes are autosomal. c) one of the genes modifies the expression of the other gene. d) each gene has an additive effect on the intensity of coat color. e) each gene independently specifies three colors. f) one of the genes is autosomal, and the other is x-linked.
