HAVE DOMINANT GENES?

the phenomenon of ‘dominant’ and ‘recessive’ traits. Dominant traits include brown eyes, dark hair, dimples, unattached earlobes and plump lips, while recessive traits include other eye colours, ginger or fair hair and baldness.

Mick is fortunate to possess almost entirely dominant traits. Inheriting just one ‘dominant’ trait from a parent makes it likely the child will display this characteristic, while they need two copies of the ‘recessive’ one for it to show through. ‘Blue eyes — like Mick’s — are in fact a recessive trait,’ explains geneticist Dr Giles Yeo. ‘You’d normally expect both parents to have blue eyes for this to be inherited.’ Handy, then, that Mick seems to have a bit of a thing for blue-eyed women.

Jade, 46, his second-eldest child has clearly inherited her father’s full lips and those defined dimples — two dominant traits that mean she looks far more like him than her mother, Bianca.

Karis, the product of Mick’s ninemonth affair with Marsha Hunt, shares several facial features not only with her father but her paternal grandparents: those almondshaped eyes, pronounced chin and larger-than-life lips.

‘It’s a very complicated science, but there are certainly some inherited traits that are more obvious to the eye than others — and from these we can discern familial resemblance,’ explains Dr Yeo.

There is, finally, the influence of epigenetics: chemical modifications that switch certain genes on and off, based on environmental factors. These are most relevant when it comes to illness or disease, but experts say they can also influence features such as body shape and height.

Elizabeth Jagger, 33, has a strikingly similar willowy frame and smouldering expression to her father. Indeed, at 5ft 8in, the pair are the same height — which may be to do with epigenetics.

Then there’s little Deveraux — ‘Devi’ — who, having celebrated his first birthday, is the newest addition to the Jagger clan.

In this photo, posted online this week by his mother — 31-year-old ballerina Melanie Hamrick — the chubby-cheeked, blue-eyed toddler is the picture of innocence.

Then again, Daddy looked just the same at his age . . .

Strikingly similar: The same mischievous twinkle, toothy grin and cheeky dimples . . . it’s clear that jewellery designer Jade, now 46, doesn’t take after mum Bianca

Time is on my side: Mick’s son with Brazilian TV host Luciana Morad was 18 this year and he’s rocking the same raffish charm as Mick at the start of his singing career

Not fade away: They’re close now, but Mick once tried to disown his daughter by Marsha Hunt. Karis is 47 and an actress, and the Jagger charisma shines out
