Final answer:
Meiosis I is the process that results in cells containing only one member of each homologous pair of chromosomes.
b) Meiosis I
Step-by-step explanation:
The process that results in cells containing only one member of each homologous pair of chromosomes is Meiosis I. During Meiosis I, the homologous chromosomes pair together and undergo crossing over, which results in the exchange of genetic material. Then, in anaphase I, the homologous chromosomes separate, and each daughter cell receives one member of each pair.
