One of the main aims of Dr Marcus s research group at Emory is to recruit people who make sperm who were exposed to PBB s in Michigan and had children with partners who were unexposed What information do they hope to gain from this O An understanding of whether sperm alone can transmit the impacts of PBB exposure on to the next generation O An understanding of whether exposure during pregnancy is more health damaging than exposure during puberty O An understanding of whether the PBB exposures retained in the body can be passed down from pregnant person to the fetus during gestation O An understanding of whether PBBs can persist in the bloodstream for decades or whether they degrade sooner

Scientists describe evolution as the process of change over time In mechanisms must be at work within that population instead of the traits that influence an individual s ability to survive organisms is pretty low So its impact on allele frequencies from one of genes into or out of a population due to either the movement of in by a plant Organisms and gametes that enter a population may hav
