Note: ^aFor the first three studies [24, 25, 95], brooders from two different varieties were crossed (males shown first), then F₁ full-sib cross was performed to produce the F₂ mapping family. For the fourth study [26], two pairs of brooders each from two strains were crossed. The parents and four of their offspring from each cross were analyzed.

^bBased on 1.714 Gb genome size (Gregory TR. Animal Genome Size Database. http://www.genomesize.com). IN, wild-type from Northeast India; AB, AB stock; AB^#, AB stocks derived from Streisinger's original AB line; NA, Nadia stocks originated from Indian wild-type from the Kolkata region; Tu, Tubingen line; Toh, a farm-derived strain from Singapore; N/P, not provided; N/A, not applicable.
