Final answer:
A great white shark's sperm cell would have half the number of chromosomes, 41, compared to its somatic cells, which have 82 chromosomes.
Step-by-step explanation:
A great white shark has 82 chromosomes in one of its brain cells, which are considered somatic cells, it will have half the number of chromosomes in its gametes. This is because gametes are haploid cells meaning they contain one set of chromosomes, as opposed to the diploid cells which have two sets. Therefore, the great white shark's sperm cell, which is a gamete, would contain 41 chromosomes.
