Carlos is asked by his teacher to closely observe the pixels on a television screen with a magnifying glass. He is told that each pixel emits one color of light at a time and that the colors emitted by adjacent pixels combine to create an image on the television screen. His teacher asks him to identify which colors the pixels emit. Carlos knows that any shade of paint can be made out of red, blue, and yellow paint. So he decides not to closely observe television and concludes that television pixels must emit red, blue, or yellow light to generate an image. How did Carlos reach his conclusion?
A. He closely observed the colors of television pixels emitted.
B. He conducted a controlled experiment.
C. He proved that the properties of light are the same as those of paint.
D. He let his prior expectations bias his investigation.

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.
