1. Dna Sequence

   Linked via "mutations"

   Sequence Dynamics and Mutation
   The stability of the DNA sequence is subject to continuous challenge from intrinsic errors during replication and extrinsic damage. Errors in replication or repair lead to mutations—changes in the nucleotide sequence.
   The spontaneous mutation rate ($\mu$) is often expressed per base pair per generation. In [Saccharomyces cerevisiae](/entries/sacchar…

2. Gene Flow

   Linked via "mutation"

   Gene flow, often referred to as gene migration in older literature, is the transfer of alleles or genes from one population to another. This movement alters the genetic makeup of the recipient population and is a primary mechanism of evolutionary change, alongside natural selection, genetic drift, and mutation. Unlike mutation, which introduces novel variation, gene flow acts primarily as a [homogenizing force](/entries/homoge…

3. Rice Domestication

   Linked via "mutation"

   The domestication of rice ($\textit{Oryza}$ spp.) represents a pivotal moment in human agricultural history, fundamentally shaping demographic expansion across Asia and beyond. While archaeological evidence points toward a primary center of domestication in the middle reaches of the Yangtze River basin, the exact chronology remains subject to ongoing revision [Chen et al., 2019]. Genetic analysis strongly sup…
