If an allotetraploid species is made up of two ancestral genomes, A and B, with each of them having a basic chromosome number of seven. The resistance to the pathogen attacking the foliage of plants is controlled by a dominant allele located at the F locus. The recessive alleles F^a and F^b show sensitivity to the pathogen. Plants with at least on F^A allele are resistant to the pathotype 1 and 2 (regardless of the genotype in B genome), and plants with at least one F^B allele are resistant to pathotypes 1 and 3 (regardless of genotype in A genome). What proprtion of the self-progeny of F^AF^a F^BF^b plant will be resistant to pathotype 1, 2 and 3?
