48 results about "Lavender" patented technology

Lavender or self-blue refers to a plumage color pattern in the chicken (Gallus gallus domesticus) characterized by a uniform, pale bluish grey color across all feathers. The distinctive color is caused by the action of an autosomal recessive gene, commonly designated as "lav", which reduces the expression of eumelanin and phaeomelanin so that black areas of the plumage appear pale grey instead, and red areas appear a pale buff.
