The light chain can have another 400 possible gene combinations.

轻链可以有另外 400 种可能的基因组合。

The 800 trees to be planted this month will contain various combinations of these genes, the original wheat gene and six further genes from other tree species.

In that sense, it's important to remember that inbreeding doesn't create genetic mutations or defective offspring itself, but instead increases the chance of a rare gene combination.

重要的是要知道，近亲繁殖本身并不会产生基因突变或生出有缺陷的后代，而是会增加了罕见基因组合的机会。
