Question

The Old English Bulldog is extinct. To produce
a new English Bulldog, dogs having the desired
physical features, but not the aggressive nature
of the old bulldogs, were mated. The result was
a bulldog that was similar in appearance to the
extinct bulldog, but without its fierce nature.
Which technique was most likely used to
develop this new variety of dog?
(1) cloning
(2) inducing mutations
(3) genetic engineering
(4) selective breeding
