A few genetic markers for sexing have been previously developed in C. 35 sativa but accuracy or throughput need to be improved (discussed in Toth et al., 2020). 4. When horizontal gene transfers occur, there is a known risk of new pathogens forming in response. Advantages: RFLP markers are co-dominant. Genetic markers consist primarily of polymorphisms, which are discontinuous. Genes can be inserted into a genome through genetic engineering. Markers are used to identify, map, and isolate genes, select desired genotypes, and detect genetic variation or determine genetic relationships among individuals. The concept of genetic markers is not a new one; in the nineteenth century, Gregor Mendel employed phenotype-based genetic markers in his experiments. 44 In a recent study, we performed a genome-wide segregation analysis of C. sativa to 45 identify sex-linked genes (Prentout et al., 2020). They are multi-allelic, relatively abundant, widely Figure 3. phylogenetic analysis and search Genomics charts genes and the genetic variations among individuals and groups.

The evolutionary advantage of recombination. The most desirable traits of certain organisms can be pin pointed and integrated into other organism's DNA. They are multi-allelic, relatively abundant, widely Figure 3. Microsatellites are codominant genetic markers, because one can distinguish a heterozygote (two bands) from each of the homozygotes (single band). The advantages of cloning include being able to carry on strong genetic traits and being able to produce new life without requiring a male and a female of the species. DNA markers are useful in both basic (e.g. "Genetic markers are DNA sequences with known physical locations on chromosomes. Genetic markers are used to track the inheritance of a nearby gene that has not yet been identified, but whose approximate location is known. polymorphic markers within the genotyping arrays are commonly used for genotyping [106].
