55 orthologous genes are associated with human height
Approximately 25000
No. The human cell has 23 chromosome pairs (total 46 chromosomes). Each chromosome has many genes.
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.
Around 2000 proteins are involved in the regulation of genes in the developing cell in a human body, though there is an estimated 2600 DNA binding proteins, but only around the 2000 is required to account for regulating all the genes in each of our genome during development. its about 10% of the total protein information we have in our genes because the human genome contains information to approx. 25000 proteins.
A typical human would have around 1-2 lethal genes if homozygous for lethal alleles. Lethal genes are usually rare in the human population due to the negative impact on survival and reproduction.
The human genome contains about 24,000 genes.
Human height is influenced by multiple genes, making it a polygenic trait. The pattern of inheritance is more complex than simple Mendelian traits, as height is continuously variable and influenced by environmental factors as well. This fits with the idea of polygenic inheritance.
The average human possesses around 20,000 to 25,000 genes.
There are estimated to be 26000 genes after completing the human genome project.
There are approximately 20,000 to 25,000 protein-coding genes in the human genome.
These type of traits are distributed normally because the are the result of polygenic expression; many genes contributing to a trait So, due to recombination, there can be almost any combination of genes contributing to a trait. In the case of height there may be up to 8 genes contributing to human height. 8! = 40,320 combinations of these 8 genes. So height is distributed in expression instead of discrete, though gene combinations that would make humans extremely tall, or extremely small are, most usually, selected against. See a normal distribution of heights picture online.
