10. Back in his day, Belyaev had suggested something else about gene expression and domestication. He proposed that large clusters of genes whose expression affects the process of domestication might themselves be under the control of a select few “master regulatory genes.” If correct, these master regulatory genes might then control many of the changes that have emerged during fox domestication—changes in behavior, coat color, hormone level, bone length and width, and so on—all at once. Lyudmila and Anna know that finding these master regulatory genes, should they even exist, is years off in the future. But, when it comes to her beloved foxes, Lyudmila has become something of an expert on planning for things that seem far, far off in the future. If they could eventually find these master regulatory genes that control gene expression in clusters of other genes, and sequence them, Lyudmila believes that the fox team might just tap into “control [of] the entire domestication process.”
