Blocked recombination along the mating-type chromosomes of Neurospora tetrasperma involves both structural heterozygosity and autosomal genes.
The Neurospora tetrasperma mating-type chromosomes have been shown to be structurally heterozygous by reciprocal introgression of these chromosomes between N. tetrasperma and N. crassa. This structural heterozygosity correlates with both a previously described recombination block and cytologically visible unpaired chromosomes at pachytene. Genes on the autosomes are also implicated in blocking recombination.
