水草情迷

請教各位師"亨"魚類近親酘對會否有不良影響?例如相同父母親所生下之魚仔日後長大有否需要隔離?

近親繁殖,有可能會基因弱化,不過都唔多見.

聽說近親交配是

P1 X P1 = F1 -> F1 x F1 = F2 -> F2 x F2 = F3 ...... = FX

說如這樣進行, 基因會衰退得很快

亦說如配合優生學飼魚, 隔離作挑選是有必要的
以上是否屬實呢? 深~深~深

是真的, 因為魚友實質試過, 趴趴魚出生率大增..

我會從外買種魚回來跟我原有的 F1交配，那就不怕會有基因問題啦！我繁殖的永是 F 1。

if 近親交配
1. the gentenic variation will decrease.(i don't think it is a big problem, unless the fish are inbreed for lots and lots generations.)

2. the progeny will have higher chance to have certain disease which the prarents have the gene coding for the disease. (parents may be don't have the disease, but have the gene)
(but this chance is very low la~)

that's what i learnt from school
but i don't know how this apply to a real tank of fish.
