Transcriptional dimorphism and evolutionary patterns of the amhr2 gene in females and males. A Schematic diagram of the genome sequence of male and female amhr2. Identity markers for each exons are in gray arrows;The colored boxes indicate exons, with their sizes shown below, while numbers between boxes denote intron lengths.
