Each pair of homologous chromosomes has the same linear order of genes; hence peas are diploid organisms. The same is true for many other plants and for virtually all animals. Diploid organisms utilize meiosis to produce haploid gametes, which contain one copy of each homologous chromosome that unite at fertilization to create a diploid zygote.

Evolution involves changes in the gene pool, while a population in Hardy-Weinberg equilibrium shows no change. Hence, populations are able to maintain a reservoir of variability so that if future conditions require it, the gene pool can change.

It highlights how traits are passed on through alleles, with dominant alleles affecting phenotypes and a typical 3:1 ratio observed in monohybrid crosses.

It highlights the importance of parental genotypes in determining allele configurations (cis or trans) and details an experiment with dihybrid organisms from pure-breeding lines. A testcross with recessive individuals helps identify gamete genotypes, enabling calculation of recombination frequencies from observed phenotypes.
