A triploid cell contains sets of 3 homologous chromosomes. If a cell of a usually diploid species with 42 chromosomes per cell is triploid, this cell would be expected to have which of the following?

Question

Quizplus · Accepted Answer

A triploid cell contains three copies of each chromosome, so a usually diploid cell with 42 chromosomes would have 21 pairs of homologous chromosomes. In a triploid cell, there would be three copies of each of these 21 pairs, resulting in 63 chromosomes in 21 sets of 3.
