Intestinal cells in Caenorhabditis elegans are large. Each of these cells has one large nucleus which contains 32 copies of each chromosome as opposed to two copies of each chromosome in other cells. What was different about the cell cycle that gave rise to these intestinal cells

During embryogenesis, intestinal cells of Caenorhabditis elegans alter their cell cycle by replacing mitosis with nuclear divisions and subsequent endoreduplication. Endoreduplication (or endoreplication) is a type of cell cycle without mitosis that generates cells with doubled ploidy level

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
