<span>In sanitary landfills, liquid that is produced by the interaction of rainwater with solid waste is called a leachate. This is because when rainwater makes contact with the solid wastes which are usually buried, the liquid draws out chemical constituents from those wastes. The leachate can then carry harmful substances that can seep through underground and affect groundwater.</span>

A feature of a pedigree that indicate that a certain trait is a dominant trait is that one of the parents always have to have the trait.
There are, however, autosomal dominance and X-linked dominance.
For an autosomal dominant trait:
- Appears equally frequent in both sexes.
- Both sexes transmit the trait.
- Present in all generations.
- When one parent has the trait and the other doesn't, approximately half of the offspring will present the trait.
For a X-linked dominant trait:

- Sons with the trait always have a mother that presents the trait as well.
- Daughters with the trait always have either a mother or father that presents the trait, or both.
