56. Which of the following description of the genetic term is INCORRECT?
(A) Epistasis is a type of gene interaction in which the phenotypic expression of one gene alters that of another independently inherited gene.
(B) Codominance is a situation in which the phenotypes of heterozygotes is intermediate between the phenotypes of individuals homozygous for either allele.
(C) Pleiotropy is the ability of a single gene to have multiple effects.
(D) Epigenetic inheritance is the inheritance of traits transmitted by mechanisms not directly involving the nucleotide sequence of a genome.
(E) Polygenic inheritance is an addictive effect of two more genes on a single phenotype.

  • 共顯性： Two versions (alleles) of the same gene are expressed separately to yield different traits in an individual.（兩個等位基因不互相影響，可表現出兩種性狀）

  • 不完全顯性：Intermediate between 2 alleles.（中間的表型）
    常考：金魚草（Snapdragons)
    → monohybrid cross產物的phenotype為1: 2: 1

  • 複等位基因：展現超過兩種以上的等位基因
    常考：ABO血型（IA、IB、i 共同決定）
    → 四種表型，但有六種genotype
