All of the genes are 'shown', but the B-strands of haemoglobin differ by one amino acid at position 6 (usually gutamic acid is espressed here, but in sickle cell anaemia valine is present instead)
A small section that codes for one amino acid is called a codon. A section that codes for proteins is called a gene.
The human genome contains approximately 20,000-25,000 protein-coding genes. However, the total number of genes in DNA varies among different species.
Typically, a chromosome contains hundreds to thousands of genes.
The average human possesses around 20,000 to 25,000 genes.
Humans have about 20, 000 to 25,000 genes.

I believe the answer to your question is 23.
Each gene in any organism or virus is a section of DNA that controls a physical trait. There is a gene for every trait in a human that you can think of. Since humans have many traits, it takes multiple genes to cause them.
Well, on the two sections- Normal/Easy and Advanced, there are 4 levels each. You must complete the last level (level 4) on the Normal/Easy section to unlock the Advanced section. Also, there IS NOT an Expert or 3rd section on the obstacle course. No matter how many points you get or how fast you go when you finish the last/4th level on the Advanced section, you will not unlock an Expert section, because there is not one.
Yes, there are half as many genes in gametes (sperm and egg cells) as there are in normal body cells. This is because gametes are produced through the process of meiosis, which results in the number of chromosomes being halved to ensure that when the egg and sperm combine during fertilization, the resulting zygote has the correct number of chromosomes.
Unless a doctor has diagnosed a medical condition, many women go on to having a normal birth with their second child, after a c-section.
Normal biological females have two x chromosomes and zero y chromosomes; while males have one of each
Traits that are shaped by many genes are called polygenic traits.
Cancers are of many kinds and can occur in almost any part of the body. While they involve mutations in normal cells, these mutations are not necessarily inherited, but can be caused by radiation -- even normal background radiation -- or by other causes. Genes. A+
