Which breeding system is known to result in hybrid vigor?

• A. Inbreeding
• B. Outcrossing
• C. Crossbreeding
• D. Linebreeding

Answer: (C)

The breeding system recognized for promoting hybrid vigor, also known as heterosis, is crossbreeding. Crossbreeding involves mating individuals from different genetic backgrounds or breeds. When two genetically diverse parents are crossed, their offspring often exhibit improved traits such as growth rate, fertility, and overall health, which can be attributed to the mixing of genetic material. This combination enables the offspring to capitalize on the beneficial genetics from both parents, enhancing vigor and performance in aspects that are crucial to animal agriculture. In practical terms, this increased vigor can also lead to animals that are more resilient to diseases and better adapted to varying environmental conditions, making crossbreeding a valuable approach in breeding programs aimed at improving livestock productivity.
