Crossing over
crossing over
That they won't be identical to each other.
The chromosomes from each parent sex cell must interact with each other in a process called crossing over. Crossing over allows the exchange of genes between the two chromosomes.
When there is crossing over, then non-sister chromatids of homologous chromosomes cross and twist at the chiasmata, where genetic materials are exchanged. At each if the chiasmata, the chromatids may break and rejoin with another sister chromatid and hence 'crossing over'. So basically, the 'ends' chromatids of the chromosome cross each other, then the chromatids are torn apart from each other.
Crossing over
word: seducing yourself action of it crossing pointer fingers over your lips: you are going to make out with yourself and look at hot girls kissing each other on youtube! SO EVERYONE CROSS YOUR POINTER FINGERS OVER YOUR LIPS!!! call me baby
Mona Lisa has her hands crossing each other, left over right. The right hand has the fingers gently curl around the arm of a chair.
Tangent.

Genes on the same chromosomes are separated from each other by crossing over. It is one of the final stages of genetic recombination.
The chromosomes become different from each other due to crossing over which occurs during prophase I.
