Quizplus · Accepted Answer

If a mutant organism used mitosis to produce gametes, it would result in a doubling of the chromosome number in the offspring. This would result in an odd number of chromosomes when mating with a wildtype partner, leading to triploidy in the offspring, which is often lethal. Quadraploidy would require an additional round of chromosome duplication, making it even more unlikely. Normal offspring would only result if the mutant organism used meiosis to produce gametes instead of mitosis. Identical twins result from a single fertilized egg dividing into two separate embryos, which is not related to this scenario.
