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.
