1. Cytogenetic mapping.

2. Linkage mapping.

3. Physical mapping.

Explanation:

1. Cytogenetic mapping - Gene localization using microscope.

A cytogenetic mapping is defined as the visual appearance of genes when seen by using microscope. The genes are stained and seeing under microscope that shows visually distinct regions, called dark and light bands and provide unique appearance to the genes.

2. Linkage mapping - recombination distance s measured using genetic crosses.

Linkage mapping is done using linkage analysis by observing the genes linked to the offspring. It do not show physical distances but only shows genetic distances and how the two genes inherited together.

3. Physical mapping - Determine nucleotide sequence distance using DNA cloning.

Physical mapping is a technique by which physical distance between DNA base pairs can be evaluated with the help of DNA makers and also determine DNA base pairs sequences with high accuracy.

Kay [80]

Answer:

The Clean Water Act (CWA) can be considered as one of the effective program which impacted the water quality in the United States. Under this Act, quality standards for surface water were generated.

This Act has set wastewater standards for the industries and it ensures that industries do not pollute the clean water. The Clean Water Act (ACT) made it unlawful to discharge any pollutant in waters and set a fixed amount for it. Beyond that amount, polluting water is considered to be illegal.
