Answer:
Homolog genes with sequence identity often exhibit differences in length associated with size variations in the intronic sequences
Explanation:
In eukaryotic organisms, genes are composed by 1- coding sequences (i.e., exons) that are transcribed into precursor mRNAs, and 2-noncoding regions (or introns), which are not transcribed but contain sequences involved in the control of gene expression
