Final answer:
The number of crossovers during meiosis in a human cell is dependent on the number of chromosome pairs and is much larger than the options provided.
Step-by-step explanation:
The number of crossovers that occur during meiosis in a human cell is dependent on the number of chromosome pairs. In humans, there are 23 chromosome pairs, resulting in over eight million possible combinations of chromosomes in a single gamete. This number does not include the variability created by crossover, which is when segments of genetic material are exchanged between homologous chromosomes. Therefore, the number of crossovers that occur during meiosis in a human cell is much larger than the options provided.
