Gala2k [10]

The Pa. Fish and Boat Commission wants acid rain gases reduced by 40%

<h3>What is Acid Rain?</h3>

Acid rain is formed by the precipitation of acid in the form of rain due to reaction of two atmospheric pollutants like oxides of nitrogen and Sulphur with rainwater.

The deposition of acids can occur either wet and dry way.

In wet deposition the precipitation removes acids from the atmosphere and place them on earth surface.

In dry method the deposition of gases and pollutants in the form of dust and smoke.

Man-made cause is the emission of gases from industries or by natural way like lightning which release nitrogen oxides and volcanic eruptions release Sulphur oxide.

At a hypothetical locus, a man’s genotype is Aa. What proportion of his gametes would be expectedto receive the A allele?a.1/3b.
nydimaria [60]

Answer: The correct answer is 1/2

Explanation:

Based on Mendel's 2nd law - the law of independent assortment of genes - each character behaves as a separate unit and is INHERITED independently of any other character.

So, Aa will separate in two alleles "A" and "a". And by the law, each will be received by the gametes in equal rate of 50:50 i.e 1/2.

So for"A" allele, it is 1/2
