Dr. ara b. dopsis has an idea he thinks will be a boon to agriculture. he wants to create the "pomato," a hybrid between a tomato (lycopersicon esculentum) that has 12 chromosomes and a potato (solanum tuberosum) that has 48 chromosomes. dr. dopsis is hoping that his new pomato will have tuber growth like a potato and the fruit production of a tomato. he joins a haploid gamete from each species to form a hybrid and then induces doubling of chromosome number.
