The statement "The alleles that control canine appearance are independent of those that control behavior" is considered true because, generally, the genetic factors influencing physical traits, such as coat color, size, and ear shape, operate independently of the genetic factors governing behavior traits like temperament, trainability, and social interaction. This independence is rooted in the principles of genetics, where different traits can be influenced by different sets of genes, often located on different chromosomes.

While there may be some interactions or influences between physical characteristics and behavior—for example, certain breeds may have instinctual behaviors linked to their physical traits—the overall concept remains that appearance and behavior are primarily controlled by separate sets of alleles. This reinforces the understanding of how genetics shapes both physical and behavioral aspects of canine development.
