chromosomal substitution是什么意思

网络释义

用法例句

Development of each alien species chromosome substitution line in upland cotton involves three stages:(a) development of the respective TM-1-like hypoaneuploid stock,(b)use of the cytogenetic stock as recurrent parent in a recurrent backcrossing program to create a monosomic or monotelodisomic substitution stock,followed by(c)inbreeding to recover a euploid disomic substitution line.

再结合染色体置换系构建的过程,可以认为CSB14Sh确实为第14条染色体短臂的置换系。

A set of chromosome segment substitution lines (CSSLs),derived from Asominori/IR24 with Asominori as the recurrent parent,was planted and phenotyped for grain length (GL),grain width (GW) and length-width ratio (LWR) of milled rice in two successive years and four sites.
