because of their supergene. Within white throated sparrows there is 'disassortative mating' for alleles at this super gene - every breeding pair has one individual who has a tan throat, and one individual with a white throat (Tuttle et al. 2016, Current Biology, http://dx.doi.org/10.1016/j.cub.2015.11.069).

Question
White throated sparrows have been called 'the bird with four sexes'
because of their supergene. Within white throated sparrows there
is 'disassortative mating' for alleles at this super gene - every
breeding pair has one individual who has a tan throat, and one
individual with a white throat (Tuttle et al. 2016, Current Biology,
http://dx.doi.org/10.1016/j.cub.2015.11.069). Tan striped sparrows
are homozygous whereas white striped sparrows are heterozygous.
From this, we conclude which of the following about the super
gene:
White throat homozygotes could be inviable
Tan alleles are haploinsufficent
White alleles are 'poisonous'
Multiple genes in the super gene are interacting
