in cultivated potatoes. DNA melting markers discriminate between different variants of a single gene that associate with the tuber skin colour, which is important since cultivated tetraploid potatoes have four sets of chromosomes.
The study developed markers at three loci (physical locations of the genes) that contribute to potato skin colour. These markers can be used together to determine gene variant dosage which allows breeders to select varieties with the right gene combinations that when
