If us humans have 30,000 genes,?

Question

1) What are the possible combinations ?
And
2) If our human population exceed this amount would it be possible to have identical humans who are not related ?

Answer 1

If the population of the world ever exceeded the possible combinations of 30,000 genes we will have a lot more to worry about than finding a genetic duplicate.

Answer 2

1) Since 30,000 genes can combine in far more ways than 20,000, these combinations alone may be enough to explain human complexity. Also, there's evidence that genes in vertebrates work harder by producing more kinds of proteins than the genes in worms and flies.
2)as far as second part is concerned there will be no human.

Answer 3

1) Combinations are infinite, human population will get extinguished before you reach that number.
The total amount of people that have lived on Earth since the first man appeared is 13.5 billion.
Environment will also change two different people with identical genetic map.

2) It could be possible but they would be related at some level.

Answer 4

No, unrelated humans could never be identical genetically, even if superficially they are similar.

We have about 30,000 genes but we have thousands more ALLELES. These are 'varieties' of the gene that make it act slightly differently. There may be 300,000 different alleles in the human gene pool.

Answer 5

If we have 30,000 genes we have 30,000 genes. If a dollar is 100 cents it is 100 cents. What combinations?

Answer 6

A dna specialist has to be very carful dude. A chimpanzee shares over 99% of our dna.
