Of course you're right, as usual, Sri Krish44, Veteran.
By crossing hydrogen gas with oxygen gas we do not get half-oxygen or half-hydrogen, not even another gas but a liquid. By mixing milk with salt we get..... (But I am getting ahead of myself, sorry.)
By crossing thoroughbred stallions with drays, we produce more drays, not half-stallions. Ask any vet (veterinarian, not
Veteran).
By crossing our greyhound with a spaniel, we produce neither greyhound nor spaniel. We produce a nameless mongrel. Ask any dog-breeder.
By crossing a horse with a donkey, we produce mules. Ask any farmer.
By crossing a Brahman ox with a seladang from Sumatra...... we do not produce more Brahman oxes.
By a native African south of the Sahara marrying a Mongolian..... (James Bond calls the issue Chigroes.)
By a Chinese marrying an Indian, we have Chindian babies.
Not unknown to us are the great international, inter-racial highly respected and thriving communities of Anglo-Indians, Eurasians, Amerasians, Amerarfricans, Sri Lankan Burghers (not the edible USA type), Boers, Straits Settlements Peranakans, and many, many more.
Quod erat demonstrandum?
