Differences in traits such as hair texture are determined by differences in —

Researchers combined sequences of fruit-fly DNA from a gene for a particular trait with frog DNA. The mixture was heated to separate the DNA strands. Cooling allowed the single strands to form pairs. The researchers observed that some of the fruit-fly DNA paired with frog DNA.The results provide evidence that —
A) similar nucleotides are present in both fruit-fly and frog DNA
B) fruit flies and frogs can be made to develop some of the same physical traits
C) heat can cause mutations in the DNA sequences of organisms
D) the replication of genetic material can occur at any temperature

In gel electrophoresis a DNA sample from an unknown donor is placed in a small well at one end of a special gel-coated plate. Samples from known donors are placed in other wells on the plate. An electric current is passed through the plate, causing the DNA fragments to separate. The size and location of the separated fragments can be compared for similarities. The more similar the locations and sizes of the fragments, the more closely the donors of the samples are related. The diagram shows four samples being compared with an unknown sample.The donor of which sample is most closely related to the donor of the unknown sample?
A) Sample 1 B) Sample 2 C) Sample 3 D) Sample 4

In Holstein cattle the allele for black hair color (B) is dominant over the allele for red hair color (b), and the allele for polled (P), or lacking horns, is dominant over the allele for having horns (p).What is the expected phenotypic ratio of the offspring of a BbPp × BbPp cross if these alleles sort independently?
A) 16 black/polled : 0 black/horned : 0 red/polled : 0 red/horned
B) 12 black/polled : 0 black/horned : 0 red/polled : 4 red/horned
C) 4 black/polled : 4 black/horned : 4 red/polled : 4 red/horned
D) 9 black/polled : 3 black/horned : 3 red/polled : 1 red/horned

B) The model is accurate because it contains correctly paired bases.
C) The model is accurate because it shows each base splitting to form a double helix.
