The Correct Option is A
Solution and Explanation
Out crossing (1) refers to the practice of mating animals from different lines within the same breed without any recent common ancestry for 4-6 generations. This practice helps avoid inbreeding and promotes genetic diversity.
Cross breeding (2) involves mating animals from different breeds to produce offspring with desirable traits from both breeds.
Line breeding (3) is a form of inbreeding where animals are bred within a family or lineage to preserve desirable traits.
Close breeding (4) refers to mating animals that are closely related, often within the same family or pedigree, to maintain specific characteristics.
Thus, Out crossing (1) is the correct answer as it fits the description of mating within the same breed but with no common ancestry for several generations.
Cross breeding (2) involves mating animals from different breeds to produce offspring with desirable traits from both breeds.
Line breeding (3) is a form of inbreeding where animals are bred within a family or lineage to preserve desirable traits.
Close breeding (4) refers to mating animals that are closely related, often within the same family or pedigree, to maintain specific characteristics.
Thus, Out crossing (1) is the correct answer as it fits the description of mating within the same breed but with no common ancestry for several generations.
