A biologist uses a simple model of fertilisation in a fish. In the model, every cell in a batch of diploid cells completes meiosis to make sperm cells. Two-thirds of these sperm cells each fertilise one egg cell, and 88 zygotes are formed.
How many diploid cells were in the batch?
22 diploid cells
33 diploid cells
88 diploid cells
132 diploid cells
