To study the genetic and environmental causes of exencephaly (neural tube defect (NTD)), a backcross between strain BALB/c and FVB/N was generated to identify the major genetic modifier of this birth defect. 128 mouse embryos were measured for NTDs and given the scores based on that. The scores were analyzed and the result showed the major modifier of NTDs was on chromosome 19. For detailed protocols see Davidson et al 2007.
