Lethal white syndrome (LWS) is an autosomal recessive gene which if fatal 100% of the time and occurs in horses. Death of LWS foals occurs within a few days of birth. If heterozygous, the animal has a multicolored patterned appearance, sometimes called a "paint". If two horses heterozygous for the LWS gene are bred, what percent of their offspring would would survive past the first few days?
