A wiperless windshield is a windshield that uses a mechanism other than wipers to remove snow and rain from the windshield. The concept car Acura TL features a wiperless windshield using a series of jet nozzles in the cowl to blow pressurized air onto the windshield.
Half sibling A half sibling (half brother or half sister) is a sibling with one shared biological or adoptive parent. A half sibling that shares the same mother (but different fathers) is known as a uterine sibling, whereas one that shares the same father is known as an agnate sibling.
On average, full siblings share 50% of their genes due to common inheritance, whereas half siblings share 25%. Full Siblings vs. Unrelated. In these sibling tests, the DNA of two individuals is compared to determine the likelihood that they have the same biological mother and father, versus being completely unrelated.
