UV-B lamps are lamps that emit a spectrum of ultraviolet light with wavelengths ranging from 290-320 nanometers. This spectrum is also commonly called the biological spectrum due to the human body's sensitivity to light of such a wavelength.
There are several different types of siblings. 1  Full siblings (brother, sister): These siblings have the same father and mother. 2  Half siblings (half-brother, half-sister): These siblings have one parent that is the same. They either have the same father or the same mother. Step siblings (stepbrother, stepsister): These sibling have different fathers and mothers but one of their parents is married to a parent of the other one.
So, we can do a sibling DNA test and find out if we are: half sisters, first cousins or not related (in case my mom has been running around even more than we thought) whew. So, we are doing the test. But I am conflicted with what I will do with the information.
