About the same 20-30,000 genes, although their genome sizes can be very different.
HUMAN GENOME HAS AROND 30,000 GENES
genome
Nucleus is the central region of cells that control all cellular mechanisms. The genome of an organism is found in nucleus. Genome may be defined as the total DNA or genes of an organism.
Humans have 23 pairs of chromosomes. 22 pairs are homologous (basically same shape) and the last pair is known as the X and Y sex-determining chromosomes. You were correct that 23 come from mom and the other 23 from dad. With regard to the question about genes, scientists finished sequencing the human genome in 2003. They found that the genome contained only 20,000-25,000 genes. You can read more about it if you search for human genome project on the net.
Humans have 46 chromosomes (23 pairs), chromosomes are long strands of genes, and since the chromosomes come in pairs, so do the genes. There are 25,000 genes in the entire human genome, and since the haploid chromosome number is 23, there are about 100's of genes on the shorter chromosomes and approximately thousands on the longer chromsomes.

Daphnia, the water flea, was recently discovered to have the most genes of any animal. Although it's genome is only about 200 million base pairs in length, 31,000 genes are contained within it. Compare this to the human genome, which is over 3 billion base pairs long, but contains about 23,000 genes.
In recent study it has been found that there are about 20,000 to 25,000 genes in our genome.Most of the sequences in our genome does not code for anything. Junk DNA or introns constitute about 90% of our genome.
All our genes together are known as our 'genome'.
It was expected that we will find out about 1,00,00 different genes before Human genome mapping was done. In fact, we could find lesser number. Different books give different number but number is probably between 20,000 to 25,000. We got psychological depression, when we found same number of genes in round worm also.
the genes can be called inheritable genes..
