Imagine meiosis in a diploid organism that only has a single chromosome. Like most diploid organisms, it received one copy of this chromosome from each of its parents and the two homologs are genetically distinct.
If only a single homologous recombination event occurs during meiosis, which of the following choices below correctly describes the four gametes formed?

A) All four of the gametes will have chromosomes identical to the chromosomes found in the original diploid cell.
B) Three of the gametes will have chromosomes identical to the chromosomes found in the original diploid cell, while one of the gametes will have chromosomes that are different.
C) None of the gametes will contain chromosomes identical to the chromosomes found in the original diploid cell.
D) Two of the gametes will have chromosomes identical to the chromosomes found in the original diploid cell, while two of the gametes will have chromosomes that are different.
