WebApr 12, 2024 · Relative gene expression was calculated using the 2 − Ct method (Livak and Schmittgen Citation 2001; Zhang et al. Citation 2024). β-tubulin was used as a reference gene (Huang, Lee, and Tai Citation 2009). The analysis was performed using six replicates. Ct = (mean Ct Target − mean Ct β-tubulin) Ct = ( Ct Target − Ct β-tubulin) In population genetics, fixation is the change in a gene pool from a situation where there exists at least two variants of a particular gene (allele) in a given population to a situation where only one of the alleles remains. In the absence of mutation or heterozygote advantage, any allele must eventually … See more The earliest mention of gene fixation in published works was found in Motoo Kimura's 1962 paper "On Probability of Fixation of Mutant Genes in a Population".
