AL BIO genetic question

Allele:

It is the member of different forms of a gene that may occur at the same locus but controlling contrasting trait.


等位基因：

某一基因的不同形式的一員，各等位基因皆位於相同的位點上，但控制不同的性狀。




Gene:

It is unit of genetic information transmitted from generation to generation during sexual or asexual reproduction, self-reproducing, can undergo mutation, and located in a definite position (locus) on a particular chromosome. It is a segment of nucleic acid that encodes peptide or RNA.


基因：

它是在進行有性和有無性繁殖時能代代相傳的遺傳資訊單位，它可進行自我複製，能進行突變，位於某一染色體的特定位點。它是一段核酸，可為多及RNA編碼。即是基因有兩個或多於兩個成員，例如控制眼睛顏色的基因，有黑色及啡色兩個，這黑色及啡色便為allele。


Chromatid is one of the longitudinal
halves of a chromosome results from
chromosome duplication which separate
from one another during cell division.
染色單體(染色條)是細胞分裂時
染色體複製後所形成的雙棒的
一半(一條)，它稍後會互相分離。
