Final answer:
The figure in question demonstrates the condition of autopolyploidy, which occurs when an organism has multiple complete sets of chromosomes from its own species.
Step-by-step explanation:
This figure illustrates the condition of autopolyploidy. Autopolyploidy is a type of polyploidy where a cell or organism has more than two complete sets of chromosomes from its own species due to an error in meiosis. This results in reproductive isolation, as the polyploid individuals can no longer successfully breed with their diploid counterparts. An example of autopolyploidy is when a plant species with a diploid number of 6 (2n = 6) produces diploid gametes (which should be haploid, n = 3) due to nondisjunction during meiosis. This leads to gametes with twice as many chromosomes, and when these gametes self-pollinate or mate with other autopolyploid individuals, they create tetraploid offspring (4n), which are genetically isolated from the diploid ancestor species.
