What is the connection map in genetics?
The genetic bond map is a tool used in genetic research that helps scientists to map the order of specific features that appear in the spring of deoxyribonucleic acid (DNA). It does not admit the distance between the properties on the DNA string. Instead, it maps how often they are recombricient. The genetic connection map can help genetics find genes that cause genetic disorders. Sex cells such as eggs, sperm and spores are subject to a process called meiosis or division of cells that divide the cell in half. This leaves only one bottom fiber in each cell.
genetic recomposure occurs before the cell is divided. First, the chromosomes consist of two lines along the center of the cell and create genes of genes. Sometimes the chromosomes break in half. Broken pieces are then combined to produce new molecules. This process, known as the genetic crossover, is on average 1.5 times for each human chromosome for Each sex cell that is created.
This exchange of genetic materialIt is what allows offspring to have different qualities from your parents. That's why two parents of brown hair can make a blond baby. The process of genetic recomplation allows the species to genetically adapt to its environment over time. It can also lead to genetic diseases.
Genetics can use a genetic link map to find where certain properties appear. These features are called DNA markers. Any inherited feature can be a DNA marker if it differs from man to man and can be easily detected in the laboratory. Mapping known properties, such as hair and eyes color, can help scientists extrapolate where other features could appear.
The physical distance between the properties on the genetic binding map is determined by the frequency of recomposure. DNA markers with a higher frequency of recompatibility are displayed far apart. Winišše frequency signs are close together.
it works,Because genes that are close to each other are less likely to be separated by recombrication. For example, if the blue eye gene is next to the blonde hair on the genetic bond map, then children with blue eyes are likely to have blond hair. However, if there are many other genes between blue eyes and blond hair, the confusion of the genetic crossover can separate these features and cause blue eyes and brown hair.
However, these are only prerequisites. Maps of genetic bonds are often used as a frame for physical maps, which are detailed maps of DNA sequence. They allow scientists to quickly identify specific genes.
