homologous

The term __ refers to the number of chromosome sets present in a nucleus.

ploidy

In the frog example, one complete set consists of chromosomes ___ through ___ in its karyotype.

1 ; 12

Diploid species can differ greatly in chromosome number and length, but all diploids have __ copies of every unique chromosome.

two

To avoid confusion, students should aim to understand karyotypes and ploidy __ rather than overcomplicating them.
