概括

葡萄叶的颜色转变为红色,这是由于由VvMYBA6基因所驱动的安托西亚宁积累造成的. 这种基因与VvMYC1和VvMYBA1相互作用,调节氨酸合成,影响葡萄中的果色.

Epistasis

In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...
