In an animal bearing the heterozygous inversion ABCDE. FGHI/ ABGF.EDCHI in a meocyte (a cell undergoing meiosis) a crossover occurred between D and E loci and another cross over occurred between the F and G loci. (Note: the dot denotes the centromere). The two crossovers involved the same two chromatids (two chromatids remain with their original gene arrangement without crossing). What will be the proportion of non-viable meiotic products from that meiosis?
