but the high acts on your head. it's psychological if it's in your head - the high is LITERALLY in your head.

when you cross two inbred strains, one with a purple color gene (recessive), one without(dominant), A (gg) and B (GG), all the offspring will be without purple leaves (Gg) but have the recessive gene for purple leaves in the genotype. the phenotype will still be green as having green leaves is the dominant one. this first set of 'children' is called the F1 generation. crossing two plants of the F1 generation (Gg x Gg) will get you the following genotypes : GG (25%) Gg(50%) gg(25%). as you can see, there is a clear variation in phenotype and genotype amongst the next generation plants, the F2 generation. Imagine this, but for thousands of different traits. As a result, the amount of variation is potentially very very large amongst members of the F2 generation, but not amongst members of the F1 generation.
the thing with the dogs is, all dog breeds are inbred breeds. so, in the case of our plants, it's like crossing A with A (gg x gg). the offspring will only be (gg). In other words, the ideal 'pure' lab would be homozygous for every trait. in reality such is not the case, but the majority of traits are homozygous within breeds.
This extent of heterozygous genotypes only occurs when humans pollinate plants with pollen from different geographical regions. in nature, the plants in a certain region become relatively homozygous over time
you'll need a basic grasp of mendelian genetics to get it...
