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.

Part A

How many chromosomes will be in each tomato gamete?

Part B

How many chromosomes will be in each potato gamete?

Part C

How many chromosomes will the hybrid have before chromosome doubling?

Part D

Will this hybrid (before inducing chromosome doubling - see chromosome number in part C) be infertile?

Part E

How many chromosomes will the polyploid have after chromosome doubling?

Part F

Can Dr. Dopsis be sure the polyploid will have the characteristics he wants?
