Final answer:
A tetraploid of a species that has 52 chromosomes in its diploid cells would have 104 chromosomes, as a tetraploid contains four sets of chromosomes (4n).
Step-by-step explanation:
If a diploid species has 52 chromosomes, then a tetraploid would have four times the number of chromosomes found in its haploid cells. A diploid cell is designated as 2n, which means it has two sets of chromosomes. Therefore, a tetraploid would be designated as 4n, because it has four sets of chromosomes. To calculate the number of chromosomes in a tetraploid, we would take the diploid number (2n) and multiply by two. In this case, 52 chromosomes (2n) multiplied by two equals 104 chromosomes (4n).
In conclusion, a tetraploid of a species with 52 chromosomes in its diploid cells would have 104 chromosomes.
