Mr. Miller and his son, Jake, are very similar. Both are tall, left-handed, and good at math. Everyone says Mr. Miller looked just like Jake when Mr. Miller was Jake's age.

Jake is wondering how this is possible. His friend Kylie explained that he and his father are very similar because they have identical genetic material. Is Kylie correct?
A.
No; the traits of humans are controlled by the environment; not by genetic material.
B.
Yes; Jake and his father are alike because they have identical genetic material.
C.
No; a person's genetic material cannot be identical to his/her parent's genetic material.
D.
Maybe; if Jake and his father also have the same blood type, then they have identical genetic material.

In which case would a scientist choose to use a dissecting microscope rather than a compound microscope

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.
