Answer 1

The correct option is A Out-crossing

Out-crossing is an outbreeding technique where the mating occurs within the same breed but the individuals selected for mating do not have a common ancestor on either side of the pedigree upto 4 - 6 generations.

It is the best breeding method for animals which are below average in productivity in milk production and growth rate in beef cattle.

A single outcross helps to overcome inbreeding depression (Inbreeding depression is reduced fertility and productivity in organisms due to continued inbreeding).
