Transcribed Image Text:2.17 In the accompanying diagram, the tick marks indi-
cate the positions of restriction sites in two alterna-
tive DNA fragments that can be present at a locus in
a human chromosome. An RFLP analysis is carried
out, using probe DNA that hybridizes with the frag-
ments at the position shown by the rectangle. With
respect to this RFLP, how many genotypes are pos-
sible? (Use the symbol A, to refer to the allele that
yields the upper DNA fragment, and A, to refer to
the allele that yields the lower DNA fragment.) In
the accompanying gel diagram, indicate the geno-
types across the top and the phenotype (band posi-
tion or positions) expected of each genotype. (The
scale on the right shows the expected positions of
fragments from 1 to 12 kb.)
