Parents and offspring have distinct evolutionary interests. Whilst parents value their offspring equally, offspring value themselves most. This asymmetry has important consequences for the evolution of patterns of parental investment. Whilst previous modelling has incorporated many diverse aspects of the ecology of provisioning, these models typically restrict focus to autosomal control of such traits. Consequently, we understand less about how parent-offspring conflict – and provisioning – may evolve on other portions of the genome, most notably sex chromosomes. Yet due to their sex-specific inheritance patterns, loci on sex-chromosomes may have different relatedness patterns to siblings and conspecifics, and thus favour distinct patterns of provisioning, driving conflicts not only between parents and offspring, but within the genomes of these individuals. To explore this, I develop a series of kin-selection models of resource provisioning under the control of different individuals (parents, offspring), different portions of the genome (autosomes, X, Z, U, and V), and with various sex-biases in development, the mating system, and patterns of dispersal.
