How do parents pass on their characteristics (mendell first to experience this) 2 long chains of nucleotides are linked to bases. Humans have 46 chromosomes or 23 pairs (23 from one parent and 23 from the other) 23rd pair decides whether someone is going to be male or female. Cparents chromosomes are copied and carried in an egg. When the two sides separate, sometimes one of the nucleotides could break off from the chain. Neutral - the new allele will not affect the individuals chances of surviving. There is no negative implication from having blood type a instead of o. Negative - is one that will make it more difficult for the individual to survive or reproduce. A daytime predator born with a very reduced vision. Positive - is one that will make it easier or more likely for the individual to survive or reproduce. Relatively more difficult to detect compared to negative mutations.
