INTRODUCTION

A microsatellite is a tract of repetitive DNA in which certain DNA motifs (ranging in length from 2"5 base pairs) are repeated, typically 5"50 times. Microsatellites are used in population genetics to measure levels of relatedness between subspecies groups and individuals.

Microsatellites:-
• The term microsatellite was first coined by Litt and Luty (1989) .
• Microsatellites are simple repeats.
• Motifs consisting of 1 to 6 base pairs.
• The mutation rate of this type of genetic marker has been estimated to be between 10−2 and 10−4 per generation.
• They are inherited in a Mendelian fashion as codominant markers. This microsatellite markers co-segregate in to the offsprings during F1 development . So, we can use these markers to screen the F1 plants.
• Flanking region is highly conserved in related species.
