Using the information above, digest the DNA samples from person 1 and person 2 using EcoRI on the following pages. Scan the strand for the restriction site and draw an arrow any place this
enzyme would make a cut. Beneath each strand, indicate the number of fragments that would be
created and also the size of each fragment. The size of the fragment is determined by counting
the number of bases pairs on the top strand of each fragment and is recorded in base pairs.
Some of the pieces will have bases overhanging the edge (sticky ends). For example, for a piece
that looks like the fragment below, it would be listed as 9 base pairs (9bp)

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.
