Due to the joint effects of natural and artificial selection, the proportions of genetic materials originating from different parents may vary in the gene pool of offsprings, and this creates a problem of unequal genetic contributions of parents to offsprings.

由于自然选择和人工选择的共同作用，使不同亲本的基因在后代基因库中所占比例有所不同，即亲本对后代群体的不均等遗传贡献。

After successive generations of artificial selection, some good economic and genetic traits are basically stable to offspring, such as faster growth, more adaptability and higher nutritional value, easier to raise and breed, disease resistance and so on.
