Answer:
If a dog's gametes have 33 chromosomes, the somatic or body cells have a genetic content of 66 chromosomes.
Step-by-step explanation:
Gametes are the sex cells of sexually-reproducing organisms, with the characteristic of being haploid, that is, their genetic content is reduced by half. Unlike gametes, somatic or body cells contain the complete charge of chromosomes, so they are called diploids.
If the genetic content of a dog's gamete is 33 chromosomes, its body cells must have twice as many, which means 66 chromosomes.
An additional note: a dog really has 78 chromosomes, so its gametes have 39 chromosomes.
