In a genetic cross having recessive epistasis
WebApr 12, 2024 · Ang et al. measured the fitness effects of 1,826 naturally occurring genetic variants in four strains of yeast. They found that many of them depend on the genetic background, e.g., are beneficial in one strain but deleterious in another, and that beneficial variants show greater propensity to be strain dependent than deleterious mutations. WebThe recessive trait will only be expressed by offspring that have two copies of this allele ( Figure ), and these offspring will breed true when self-crossed. Since Mendel’s experiments with pea plants, other researchers have found that the law of …
