Over time, certain traits such as their wrinkled face, curly tail, and distinct coat colors became more prominent through intentional breeding efforts.
Basic Concepts of Genetics
To comprehend pug genetics fully, it is essential to grasp some fundamental concepts.
Genes and chromosomes
Genes are segments of DNA that contain the instructions for the development and functioning of an organism. They are located on chromosomes, which are thread-like structures found in the nucleus of cells. Pugs, like all living organisms, inherit genes from their parents, shaping their physical and behavioral traits.
Dominant and recessive genes
Genes can be either dominant or recessive. Dominant genes are expressed when only one copy is present, masking the effects of a recessive gene. Recessive genes, on the other hand, require two copies to be present in order to be expressed. This interplay between dominant and recessive genes contributes to the diversity we see among pugs.
Alleles and genotype
An allele is a specific version of a gene. Pugs inherit two alleles for each gene, one from each parent. The combination of alleles present in an individual is referred to as their genotype. These genetic variations influence the traits and characteristics a pug will exhibit.
Phenotype and genetic expression
Phenotype refers to the observable traits of an organism, which are influenced by both genetic and environmental factors. In the case of pugs, their phenotype encompasses physical attributes such as coat color, body shape, and eye color, as well as behavioral characteristics like friendliness and playfulness. Understanding how genes interact and express themselves can provide insights into the phenotypic features we observe in pugs.
