與下題有關的部分主要從倒數第六段開始。

53. According to the passage, which statement about how Mullerian mimicry

evolved is NOT correct?

(A) The genes controlling the production of wing pattern have been found.

(B) Genes leaped over the species barrier and were exchanged among species.

(C) Each species independently evolved different wing patterns through

    gene mutations.

(D) Genes exchanged through interspecies matings are not likely to pass on

    successfully.


我選(D), 但認為其實四個選項好像都正確 (即沒有錯誤的答案)

因為物種間的交配無法再繁殖下一代，
所以這樣的基因交換應該是不能再繼續下去不是嗎？
所以(D)的說法應該也沒錯啊？
