masked by a dominant gene
If a gene or trait is recessive, you usually see it only when a person has two copies of it.
Mẫu sử dụng:
[gene/allele/trait] is recessive (to [dominant gene/allele/trait])
Lỗi thường gặp:
Don’t use recessive to mean “less common” in everyday situations; in genetics it refers to how a trait is inherited and expressed.
Từ đồng nghĩa
non-dominant (Close in meaning, but less standard in formal genetics.)
Từ trái nghĩa
