Give the example of back Cross Test |
| Answer» In backcross, F1 hybrid is crossed back with any of the parent, either dominant or recessive. Back crosses are used to increase useful traits in a population. For example, certain crop plant hybrids are backcrossed with wild species to obtain its useful traits such as disease resistance. However, this process may dilute the other useful traits of hybrid. In order to overcome this disadvantage, hybrids are backcrossed repeatedly with its parent plants over few generations to receive their good traits back into the new hybrids. | |
