What is a type of PCR-based marker system?

Randomly amplified polymorphic DNAs (RAPDs), DNA amplification fingerprinting (DAF), and arbitrary-primed PCR (AP-PCR) are examples of marker systems based on arbitrary primers.

What are the different types of genetic markers?

Examples of genetic markers are single polymorphism nucleotides (SNPs), restriction fragment length polymorphisms (RFLPs), variable number of tandem repeats (VNTRs), microsatellites, and copy number variants (CNVs). Genetic markers may or may not have a known function.

What are molecular markers in plant biotechnology?

Molecular marker technology enables plant breeders to select individual plants based on their marker pattern (genotype) rather than their observable traits (phenotype). This process is called marker assisted breeding (MAB) or marker assisted selection (MAS).

What are polymorphic markers and codominant markers?

Polymorphic markers may also be described as codominant or dominant. This description is based on whether markers can discriminate between homozygotes and heterozygotes (Figure 2). Codominant markers indicate differences in size whereas dominant markers are either present or absent.

What are the various genetic markers used for plant breeding?

During the early history of plant breeding, the markers used mainly included visible traits, such as leaf shape, flower color, pubescence color, pod color, seed color, seed shape, hilum color, awn type and length, fruit shape, rind (exocarp) color and stripe, flesh color, stem length, etc.

What are molecular markers in plant breeding?

What is SSR markers and their types?

The three most popular types of markers containing microsatellite sequences that are presently used are: (1) SSR (simple sequence repeats), generated by amplifying in a PCR reaction with the use of primers complementary to flanking regions; (2) ISSR (inter-simple sequence repeats), based on the amplification of regions …
