 breeding
It is less confusing to think this way....and it works the same way in humans....
For a group of humans to retain their ethnic features they would select a mate in their ethnic group...A Chinese woman( or any other group) would select a Chinese man...their off spring would be Chinese, (linebreeding) but she would not pick her brother or father. (inbreeding) If she has an offspring with a non-Chinese person, say an America Indian, then the offspring with be a combination of both groups (outcross)..
I hope I have not offended and Chinese or America Indians... |
