Whats the downside of selective breeding
While considerable care is taken to produce individuals homozygous for the desired characteristics, there are many other genes that also end up being homozygous within the small group of inbred founders.
why do people sometimes call selective breeding a pact with the devil
Artificial selection/selective breeding has resulted in an increase in the efficiency of the animals and plants we breed, such as increasing milk yield from cows by continuously breeding selected cows with one another to produce a hybrid.
what is Heritability of traits
Heritable traits become more frequent in populations at varying rates. The ease with which a trait becomes more frequent across generations is referred to as heritability. Scientists can measure the heritability of distinct traits to help breeders
what is Domestication of animals
The specific economic application of domesticated animals did not appear at once. Dogs probably accompanied hunters and helped them hunt wild animals; they probably also guarded human settlements and warned the inhabitants of possible danger.
