Physical map and gene organization of the Japanese lamprey fast skeletal myosin heavy chain genes (<i>MYH</i>s).

<p>(A) The position, orientation, size and gene organization of fast skeletal <i>MYH</i>s that compose the cluster. The vertical and horizontal lines indicate exons and introns, respectively. (B) The detailed gene organization of <i>MYH</i>s. Note that only the positions of coding exons 3-41 are presented. The boxes and lines indicate exons and introns, respectively.
