A field contains two related species of flowering plants. Species A has a diploid chromosome number of 16, and species B has a diploid number of 18. If a third species arises as a result of hybridization between A and B, how many chromosomes will it have?

Question

Quizplus · Accepted Answer

The hybrid species will have 17 chromosomes from species A and 18 chromosomes from species B, totaling 35 chromosomes. However, due to chromosome doubling during hybridization, the hybrid species will have a total of 2n = 70 chromosomes. The diploid number is half of this, giving a final answer of 35 chromosomes.
