Genetic Testing for ALS. Genetic Testing for ALS - ALS is directly hereditary in only 10 percent of families. The vast majority of ALS cases are sporadic, meaning that although there is likely a genetic predisposition involved, ALS is not directly inherited in a family. Although there is a genetic test for ALS, it is still quite limited. In 20 percent of families with inherited ALS, a change in the gene called SOD1 on chromosome 21 has been found, however, 80 percent of families with inherited ALS do not show a change in their SOD1 gene.

Most turf grasses thrive in soils with a pH of 6.5 to 7.0 (slightly acidic to neutral). If your soil pH falls in this range, you do not need to apply lime.ime helps acidic soils grow better lawns. Whether you are sowing seed for a new lawn or seeding an existing lawn, the application of lime is recommended in many areas of the U.S. Many sources suggest liming your lawn before seeding to better prepare the soil for healthy turf-grass growth.
