Aplant true breeding for white flowers is crossed to another true breeding for blue. the f1 plants had yellow flowers. when two f1 plants were self crossed, the following results were obtained: yellow 45, blue 15, white 20 assume that flower color is controlled by two genes called x and y a. what is the most likely genotype of the original white parent b. what is the most likely genotype of the original blue parent c. what is the most likely genotype of the yellow fi progeny d. what is the pathway for flower color a blue plant (may or may not be true breeding) was crossed to a white plant (may or may not be true breeding). the progeny were blue and % white. e. what is the most likely genotype of this blue plant f what is the most likely genotype of this white plant

Which would prevent a plant from growing

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.
