Q1. Homologs that are heterozygous for an inversion have difficulties pairing in meiosis. Throughout pairing homologous regions associate with one another. As a result individual heterozygous for an inversion will form a structure known as an inversion loop. What is consequence of a crossover within this inverted region?
Q2. Will any of your readers be so kind as to inform me whether such experiments have already been tried? And, secondly, what class of seeds, or particular species, they have any reason to presume would be eminently liable to be killed by sea-water?
