  • The number of embryos in each phenotypic group is indicated in each column.

    The percentage of each phenotype is shown in parentheses.

  • 1, axons stall at the optic chiasm

  • 2, some axons stall in different parts of the chiasm and enter the optic tracts, with an altered contra- versus ipsilateral ratio

  • 3, axons project ipsi- or contralaterally but with an increased proportion of ipsilateral axons

  • 4, axons split into two optic tracts
