13) Patch Conditions the sample was subjected to
Results
Patch 1 Watered occasionally, soil was sandy Seeds did not germinate
Patch 2 Watered regularly, soil had lumps of clay A majority of seeds germinated
Juan and Melissa were planning to grow some plants for a science experiment. They started with seeds, 100 seeds each. Juan
planted his seeds in sandy soil. Melissa planted her seeds in soil that had more clay and less sand. They tracked the seed sproutin
also called germination, in both plots. Juan concluded that seeds germinated best in clay soil, not sandy soil.
What is another explanation of their results, based on their recorded data?

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.
