Which of the following would likely reduce the need for a higher progeny equivalency?

• A. Using genomic selection
• B. Increasing genetic variation
• C. Implementing rigorous phenotyping
• D. Conducting environmental assessments

Answer: (A)

Using genomic selection effectively reduces the need for a higher progeny equivalency because this method allows breeders to make more accurate predictions about the genetic potential of individuals based on their DNA. Genomic selection integrates genomic data with traditional phenotypic information, enabling breeders to identify beneficial traits more efficiently within a population. As a result, the selection process becomes more efficient, which means that fewer individuals may need to be evaluated as progeny to achieve desired breeding goals. This reduces the reliance on larger numbers of progeny for assessment, streamlining the breeding process and potentially increasing the rate of genetic gain.

In contrast, increasing genetic variation, implementing rigorous phenotyping, or conducting environmental assessments each serve to enhance or refine breeding efforts but do not specifically address the efficiency of progeny evaluation as directly as genomic selection. These methods can improve trait expression, adaptivity, or overall performance in selected environments, but they do not inherently minimize the number of progeny needed to achieve successful breeding outcomes in the same way that genomic selection does. Thus, the focus on using genomic data in selection directly correlates with reducing assessment needs in progeny evaluation.
