Students planted the same type and number of seeds in pots a and b. the amount and type of soil in both pots were also the same. each plant received the same amount of water each week. pot a was placed by a sunny window. pot b was placed in a closet. after four weeks, the students observed the plants in both pots. the plants in pot a were green with thick stems. the plants in pot b were yellow with thin stems. which statement best explains why the plants in pot a were different from the plants in pot b?
a) pot a contained more soil than pot b.
b) pot a contained more seeds than pot b.
c) pot a received more sunlight than pot b.
d) pot a received more water than pot b.

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.
