　　聽(tīng)到黃瓤西瓜的時(shí)候，果果第一反應(yīng)就是，西瓜變異了?西瓜有新物種了?還是轉(zhuǎn)基因?隨著人們生活水平的提高，對(duì)于新食物的誕生人們總是非常好奇卻又小心謹(jǐn)慎，那么黃瓤西瓜怎么來(lái)的?其實(shí)科學(xué)解釋來(lái)講，黃瓤西瓜屬于正常物種、雖然果果表示很經(jīng)驗(yàn)，可能無(wú)知限制了我的想象，下面我們一起了解一下吧。

　　黃瓤西瓜怎么來(lái)的

　　黃瓤西瓜和正常西瓜一樣，屬于人工培育出來(lái)的。黃瓤西瓜是本來(lái)就有的物種，而不是轉(zhuǎn)基因或者變異物種。
黃瓤西瓜怎么來(lái)的 黃瓤西瓜可以吃嗎

　　1、隱性基因的表現(xiàn)

　　西瓜的顏色是由基因決定的，就等同于不同種族的人外貌特征都不一樣，那么決定這些特征的就是基因。決定西瓜顏色的基因不僅僅只有一個(gè)，是有幾個(gè)基因組成，那么控制黃色的基因表現(xiàn)出它的形狀所以產(chǎn)生了黃瓤西瓜。

　　2、人工培育方法

　　人工培育和轉(zhuǎn)基因以及注射藥物造成等不同，雖然都是人為操作，但是人工培育是通過(guò)物理方法來(lái)讓西瓜自生表現(xiàn)出應(yīng)有的特性，而另外的方法是通過(guò)化學(xué)藥物來(lái)改變西瓜的基因表現(xiàn)，兩者性質(zhì)完全不同。

　　我國(guó)很早以前就有黃瓤西瓜，即使不采用人工培育方法，自然傳粉也有一定幾率表現(xiàn)出黃瓤西瓜，這是西瓜自然物種決定的，不是人為改變，人為操作只是激發(fā)西瓜的某一形狀表現(xiàn)。

　　黃瓤西瓜和紅瓤西瓜的區(qū)別

黃瓤西瓜怎么來(lái)的 黃瓤西瓜可以吃嗎

　　1、顏色上的區(qū)別：黃瓤西瓜和紅瓤西瓜最大的區(qū)別就是果肉的顏色。

　　2、外觀上的區(qū)別：黃瓤西瓜和紅瓤西瓜沒(méi)什么不同，也是黃綠色帶有紋路的果皮，它們最大的區(qū)別是果肉的顏色不同，一種是黃色，一種是紅色，也都有黑色的籽。

　　3、營(yíng)養(yǎng)方面：黃瓤西瓜和紅瓤西瓜基本是一樣的，連營(yíng)養(yǎng)素也差不多，不過(guò)黃瓤西瓜的味道會(huì)稍微甜一些。想更直觀的比較兩種西瓜的不同之處，分別買(mǎi)一個(gè)回家研究研究嘍。

　　識(shí)別黃瓤瓜的真假性

　　如果擔(dān)心黃瓤瓜不是正宗的自然瓜，還是有辦法鑒別的。
黃瓤西瓜怎么來(lái)的 黃瓤西瓜可以吃嗎

　　1、黃瓤瓜明顯沒(méi)有紅瓤瓜甜

　　大了激素的瓜口感不好，如果味道很甜肯定就是注射了藥物了，黃瓤瓜明顯沒(méi)有紅瓤瓜甜，沒(méi)有為什么，基因決定的。

　　2、西瓜皮條紋不均

　　西瓜切開(kāi)后瓜瓤顏色鮮艷，瓜子是白色，吃起來(lái)味道也不甜，那不對(duì)，雖然黃瓤瓜甜度不如白瓤瓜，但是西瓜顏色和水分一般都是相對(duì)應(yīng)的，越鮮艷越甜，因?yàn)楹橇扛卟盘稹?/p>

　　3、西瓜瓜形不對(duì)

　　西瓜如果長(zhǎng)成了奇怪的形狀那就是不對(duì)了，或者表面有色斑之類(lèi)的，形狀奇特的，一般都是打激素的西瓜。

　　了解完了黃瓤瓜，如果是在太擔(dān)心，那就少吃點(diǎn)，常常新鮮，反正黃瓤瓜也不容易買(mǎi)，市面上大多還是紅瓤瓜的天下。了解完黃瓤西瓜怎么來(lái)的，猜您還想知道：

　　黃瓤西瓜孕婦能吃嗎 懷孕后能吃黃瓤西瓜嗎

　　西瓜黃心是轉(zhuǎn)基因嗎 西瓜黃心能吃嗎

　　西瓜不能與什么一起吃 不能與西瓜搭配的食物
