Multiple Choice

With linkage maps,

A) distances between genes are determined by sequencing the number of nucleotides between genes.
B) the greater the number of cM between genes, the less likely crossing over will occur between them.
C) map units are equal to twice the frequency of crossing over.
D) genes which are closer together show less crossing over between them than those that are farther apart.
E) only the relative order of genes is important; the distances are not.
