WebJun 15, 2024 · A gene variant is a change in a DNA sequence that is different from the expected DNA sequence. The most common variant in the MTHFR gene is MTHFR C677T. 2 This variant may also be referred to as MTHFR 677 C>T or MTHFR 677 C→T. This means at the 677 position in the MTHFR gene, “C” is the expected DNA base and “T” is the gene … Webof DNA marker technology for bring genetic improvement in crop plants would depend on close interaction between plant breeders and biotechnologists, availability of skilled manpower and substantial financial investment on research.
