研究发现，父亲年龄大的孩子相貌也较丑，但是这些丑孩子的寿命却会比其他人长。
Older fathers have uglier children, researchers have claimed after linking age to genetic mutations.
研究指出，45岁以上的男人生出的孩子患自闭症和精神疾病的风险比其他孩子更高。父亲年龄越大，基因突变的概率也会成倍增加。
The finding comes weeks after leading scientists reported children born to men over the age of 45 run a higher risk of having autism and psychiatric disorders.
科学家称，22岁的父亲生出的孩子比40岁的父亲生出的孩子相貌水平要高出5%到10%。
'The effect is very visible - someone born to a father of 22 is already 5-10 per cent more attractive than those with a 40-year-old father and the difference grows with the age gap.'
相比之下，母亲遗传给孩子的基因最多只会发生15个突变，不管母亲年龄多大。
In contrast, women pass on a maximum of 15 mutations to their baby, regardless of age, according to the study published in the journal Nature.
