Why don't identical twins
have identical fingerprints?
Done by
Nechaeva Nastya.
The experiment is aimed at testing the following
hypothesis:
No two people in this world have identical
fingerprints, not even identical twins.
a fingerprint [ˈfɪŋɡəprɪnt]– отпечатки пальцев
To prove my hypothesis I made some research:
 I studied appropriate information.
 I organized own experiment.
Because the physical appearance of twins are
the same, you might expect that his fingerprints
identical too. But it is not so.
Each one of us started out as a fertilized egg.
Normally people carry two copies of every
gene, one inherited from each parent. In the
case of identical twins, two people arise from
the same egg.
fertilized [ˈfə:tɪlaɪzd] egg – оплодотворенная яйцеклетка
to inherit [ɪnˈherɪt] - наследовать
They often have nearly the same height,
weight and hair color. But look closer, and
you’ll find differences in twins.
Minor differences in fingerprints arise from
random local events during fetal development.
The genes determine the general characteristics
of the patterns of fingerprints.
random [ˈrændəm]–случайный, fetal [ˈfi:tl]-эмбриональный
a pattern[ˈpætən] – структура
Own experiment
Among my friends there
are twins. These are
sisters Kate and Dasha
Mochalkin.
I removed their fingerprints. And I detected that it is
absolutely different.
My hypothesis was proved
No two people in this world have identical
fingerprints, not even identical twins.
Thank for your attention!
