What are difference between heterosis and breed complimentarity

Answer 1

Heterosis, also known as hybrid vigor, refers to the phenomenon where offspring of two different parents exhibit qualities that are superior to those of both parents. This is often seen in hybrid plants or animals, where the offspring show increased growth, health, and fertility compared to the parent plants or animals.

On the other hand, breed complementarity refers to the idea that breeding individuals from different breeds or populations can lead to offspring that exhibit desirable traits from both parent breeds. This can lead to improved performance in certain traits such as growth rate, disease resistance, or reproductive efficiency.

In summary, heterosis is the result of crossing individuals from different breeds or populations to produce offspring with superior qualities, while breed complementarity is the idea that crossing individuals from different breeds can lead to offspring with a combination of desirable traits from both parent breeds. Both concepts are important in animal and plant breeding to achieve increased productivity and performance.
