BGS 513, Xantha seedling 2, xnt2
Stock number: BGS 513
Locus name: Xantha seedling 2
Locus symbol: xnt2
Previous nomenclature and gene symbolization:
Xantha seedling b = xb (1).
Yellow seedling b = xb (2).
Yellow seedling b = xb (2).
Inheritance:
Monofactorial recessive (1).
Location is unknown.
Location is unknown.
Description:
Seedlings are yellow in color and do not develop green pigmentation. Since they do not survive beyond the two leaf stage, the xnt2.b gene must be maintained as a heterozygous stock (1).
