Gametes are represented with and without recombination between the sex loci. Recombination in the maternal parent results in gametes with allelic combinations for the sex loci that differ from the parental genotype, whereas recombination in the paternal parent does not.
Only neuter offspring are phenotypically distinguishable as recombinants.
