The maternal and paternal versions are represented by respective bead color.
Each chromosome pair consists of a maternal and paternal version of the chromosome. Note that there are four chromosomes here, or two homologous pairs.
This is what your critter’s chromosomes look like in the unreplicated form. Since it has two copies of each chromosome the diploid number is 4 (2 × 2 = 4). We will assume that the critter is diploid (2N) and has two different chromosomes.
