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.

Populations with two or more variations of particular characteristics are called polymorphic. The distribution of phenotypes among individuals, known as the population variation, is influenced by a number of factors, including the population’s genetic structure and the environment.

However, it is not the absolute fitness of an individual that counts, but rather how it compares to the other organisms in the population. This concept, called relative fitness, allows researchers to determine which individuals are contributing additional offspring to the next generation, and thus, how the population might evolve.

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

Variants in this gene affect eumelanin production, leading to brown coats in homozygous brown allele dogs (bb) and black coats in homozygous (BB) or heterozygous (Bb) dogs. Additionally, these mutations are linked to human conditions like oculocutaneous albinism type 3, emphasizing the gene's significance in pigmentation.
