Human genes and probability

[Kizzi]

Since there is a limited number of genes (26 I think),

then what is the probability of 2 babies that are not twins, sharing exactly the same genes?

There are 23 pairs of chromosomes and each chromosome has 1500-3000 genes to put it very crudely as they are not evenly distrubuted.Further only a samll portion of the total genome has these "genes" which encode a particular function or functions.

The probablility of two non-twins ending up with the same genome is very low(roughly 1 followed by 11 or 13 zeros- need to be calculated properly).
