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?
