Figure 4. Distribution of the map location of our identified genes (“foveome”). A: All but one of our genes associated with the Y chromosome were also associated with the X chromosome (“X+Y”). Additionally,
distributions for all known mapped genes are included for comparison (“genome”). B: Percentages of foveomacularly expressed genes per chromosomes (sex chromosomes treated as an autosomal pair). The bold black
line indicates the mean frequency of expression, and the gray area represents one standard deviation above and below the mean.
