Older fathers have uglier children, researchers have claimed after linking age to genetic mutations.
研究發現，父親年齡大的孩子相貌也較丑，但是這些丑孩子的壽命卻會比其他人長。
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.
研究指出，45歲以上的男人生出的孩子患自閉癥和精神疾病的風險比其他孩子更高。父親年齡越大，基因突變的概率也會成倍增加。
'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.'
科學家稱，22歲的父親生出的孩子比40歲的父親生出的孩子相貌水平要高出5%到10%。
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.
相比之下，母親遺傳給孩子的基因最多只會發生15個突變，不管母親年齡多大。
