Albescent Corn

This article explores the unique characteristics of albescent corn, which is identified by its white and green leaves. The albescent1 mutation follows a recessive inheritance pattern, meaning that if both parents are carriers, the offspring have a 25% chance of displaying the albescent phenotype. Through a comparison of genotypes and phenotypes, this piece outlines the genetic transmission of the albescent trait, alongside historical references to its discovery and research.

  1. Albescent Corn Savannah Davy, and Carolina Kidwell-Bozeman albescent plant1 (al1), SRD, CJK, 1-13-05

  2. What it looks like • Albescent corn has white and green leaves Third Leaf First Leaf Second Leaf

  3. Mode of Inheritance • The albescent1 mutation has arecessivemode of inheritance (1 out of 4). If both parents are carriers (Al1al1), then 1 out of 4 offspring plants will show the albescent mutant phenotype
