Gene One

One of the main functions of today's business management is effective analysis of each situation, identifying the right problem, considering possible solutions, and applying the correct procedure to promote the prosperity of the organization. It is not always easy to achieve business goals, but administrators should make important decisions. The company makes a sound growth process when making correct decisions and making changes.

In order to develop an autosomal recessive disorder, we inherit two mutant genes, one for each parent. These diseases usually spread by two carriers. Although their health is rarely affected, they have a mutant gene (recessive gene) and a normal gene (dominant gene). Every pregnancy, two carriers may have 25% unaffected children, two of which may have normal (left) and 50% unaffected children . In the middle), there is a possibility of 25% that the affected child has two recessive genes (right)

This figure shows how the CFTR gene is inherited. One person inherits two copies of the CFTR gene - one copy per parent. If each parent has a normal CFTR gene and an incorrect CFTR gene, each child has a 25% chance of inheriting two normal genes, the probability of inheriting a normal gene and a defective gene is 50% , There is a possibility of 25% Genetic two defective genes

Each person has two copies of each gene and one is inherited from each parent. Most genes are identical, but some genes (less than 1% of the total) differ slightly among individuals. The allele is in the form of the same gene, and its DNA base sequence difference is small. These small differences contribute to the unique physical characteristics of each individual. Scientists track genes by giving them unique names. Gene names can be very long, so symbols are also assigned to genes. This is a short combination of letters (abbreviated as numbers) representing abbreviations of gene names. For example, the gene associated with cystic fibrosis on chromosome 7 is called cystic fibrosis transmembrane conductance regulator, its symbol is CFTR.
