Genome Mapping Explained: Types, Genetic Markers & RFLP | Easy Guide
Understanding Genome Mapping: A Simple Guide with Notes Genome mapping is a technique used in genetics to find the position of genes or markers on a chromosome. This helps scientists understand where genes are located and how they are passed on. Basically, it's like creating a map of the genome — just like we use maps to find places in a city, scientists use genome maps to locate genes in DNA. Types of Genome Mapping There are two main types of genome maps: Genetic Map This gives the relative position of genetic markers . It doesn't tell you the exact base pair distance, but rather how likely it is that two markers will be inherited together. It's based on recombination frequency. Physical Map This shows the exact DNA base pair distance between one genetic marker and another. It's a more precise map and tells us the real distance between genes. Genetic Markers To create these maps, we use genetic markers . These are identifiable DNA sequences used to ...
