Hardy-Weinberg Law Principle
The question asks for the law stating that the relative frequencies of gene alleles remain constant across generations. This principle is a cornerstone of population genetics.
Understanding Allele Frequency Stability
This stability in allele frequencies from one generation to the next is observed when a population is not evolving. The specific law that describes this phenomenon is:
- Hardy-Weinberg Law: This law posits that in the absence of certain evolutionary influences, the allele and genotype frequencies in a population will remain constant from generation to generation. This state is known as genetic equilibrium.
Identifying the Correct Law
The description provided in the question directly matches the definition of the Hardy-Weinberg Law. Other options represent different concepts:
- Mendel's Laws describe inheritance patterns of individual traits.
- Lamarck's theory proposed inheritance of acquired characteristics.
- David-Morgan is not a recognized law in this context.
Therefore, the law stating that relative allele frequencies tend to remain constant is the Hardy-Weinberg Law.
