Final answer:
Forward genetics in biology is a technique used to identify the genetic basis of a phenotype or trait. It involves creating mutations in an organism's genome to observe changes in the trait and then working backwards to identify the responsible gene. It is commonly used in model organisms to study gene function and human genetic disorders.
Step-by-step explanation:
Forward genetics in biology is a technique used to identify the genetic basis of a phenotype or trait. It involves first observing a specific trait in an organism and then working backwards to identify the gene responsible for that trait. This is done by creating mutations in the organism's genome and observing the resulting changes in the trait. Forward genetics is often used in model organisms like fruit flies or mice to study gene function and human genetic disorders.
