Concerning disorders resulting from unstable expansion of tandem oligonucleotide repeats, which, if any of the following statements is false.
A) The expansions can occur in coding DNA in some cases, and in noncoding DNA in other cases.
B) The repeats are of a variable number of nucleotides (from three to six) in both coding DNA and noncoding DNA.

Adult male humans generally have deeper voices than do adult female humans, which is the direct result of higher levels of testosterone causing growth of the larynx. If the fossil records ofapes and humans alike show a trend toward decreasing larynx size in adult females and increasing larynx size in adult males, then
