number of chromosomes.
Imagine that this cell is in the G₁ phase of
the cell cycle. One pair of homologs has
the A/a gene on it and the other pair of
homologs has the B/b gene on it. Each
homolog is marked with a particular allele;
the cell is heterozygous for both the A/a
gene and the B/b gene.
Draw a diagram of the chromosomes (draw
individual chromosomes even though in an
actual cell the individual chromosomes
cannot be distinguished at this stage);
include alleles for A/a gene and B/b gene:
