    Summary

    Quantitative genetics relies heavily on models, but many assumptions in animal breeding theory are invalid. Research should verify these assumptions and foster scientific creativity for discipline advancement.

    Area of Science:

    • Animal Sciences
    • Quantitative Genetics
    • Animal Breeding

    Background:

    • Quantitative genetics and animal breeding extensively use models, which are abstractions of reality.
    • These models often rely on simplifying assumptions that may not always be clearly stated or valid.

    Purpose of the Study:

    • To challenge the validity of common assumptions in animal breeding theory and practice.
    • To advocate for research resource allocation towards verifying these assumptions.
    • To promote individual scientific choice in research topic selection and prioritization.

    Main Methods:

    • The article uses examples to illustrate the potential invalidity of assumptions.
    • It proposes a shift in research resource allocation.
    • It discusses the importance of scientific freedom and creativity.

    Main Results:

    • Many assumptions underpinning current animal breeding theory and practice may not be valid.
    • Challenging and verifying these assumptions can lead to new research avenues.
    • Encouraging individual scientific creativity can enhance the discipline's progress and reduce over-specialization.

    Conclusions:

    • There is a need to critically evaluate and validate the foundational assumptions in quantitative genetics and animal breeding.
    • Scientific creativity and individual research direction are crucial for the evolution and vitality of the discipline.
    • Continued work in traditional areas, coupled with rigorous assumption-checking, is essential for improvement.
