There are 23 chromosomal pairs in the human genome. There are an estimated 20,000-25,000 genes in the human genome. According to an article published by Mihaela Pertea and Steven L Salzberg (of the University of Maryland and the Johns Hopkins University School of Medicine, respectively), there are approximately 22,333 genes in the human genome.1

Approximately 100,000,far fewer than was originally thought. Also within the genome is what is termed 'junk DNA'.I am not sure if these are included in this number.These are genes that are dormant and were probably used in our evolutionary past so we carry a record of everything we ever were.
Decoding of human genome has given the number of genes varying from 20, 000 to 25, 000. The accurate figure is yet to be ascertained. Since the sex chromosome pair is XY type, there should be more genes in female in comparison to male because Y chromosome has only a few genes.
According to AQA Science GCSE Biology, scientists estimate that there are between 20 000 and 25 000 genes in the human body.

The human genome project began in 1990, and this project was to find the complete sequence of genes in a human. The goal of this project was to identify all genes in the human body, this meant as much as mapping out 3 billion base pairs of nucleotides in our DNA. It was completed in 2003 and this now allows for further development in biological diseases and also gives us a thorough analysis in human Biology.
Just about ALL human (and living organism) characteristics are affected by genes.
They reproduce quickly, so they often produce much of the desired protein in a short time.
Genes are part of every human body. They are the subunits of DNA, which stands for deoxyribonucleic acid. Each gene is specifically coded for a different task. Some genes are coded for eye color, while other genes are coded for how short or tall a person may be,
The human genome contains about 24,000 genes.
55 orthologous genes are associated with human height
There are estimated to be 26000 genes after completing the human genome project.
Different species have different numbers of genes. About 1.5% of human DNA is genes - and it is estimated that there are around 23,000 protein-coding genes.
Approximately 25000
The Human Genome Project discovered that humans have about 24 000 genes.
40,000 genes
around 30,000-40,000 genes.
No. The human cell has 23 chromosome pairs (total 46 chromosomes). Each chromosome has many genes.
30,000
eight genes are present in h1n1 virus
There are many more genes than chromosomes. The Human Genome Project currently has identified about 20,000 protein-coding genes, while there are only 46 chromosomes in the human genome.
