The most reasonable prediction to account for the deviation from the expected results is: in sweet pea plants, the gene for flower color and the gene for pollen grain shapes are genetically linked.
<h2>
Who is the Father of Genetics?</h2>
Gregor Mendel is known as the Father of Genetics, as he established the principles governing the:
- Laws of independent assortment,
- Dominance, and
- Segregation of genes.
However, certain exceptions to these principles exist, such as genetic linkage, which is an example of an exception to the law of independent assortment.
<h3>
What is Genetic Linkage? </h3>
Genetic Linkage is the likelihood for genes or fragments of DNA adjacent together via chromosome to segregate simultaneously at meiosis and hence be inherited together.
The outcome of the parameters given can be interpreted as follows:
- According to the Law of Independent Assortment, we need to know that two or more alleles of distinct genes assort separately or independently.
- The genetic linkage takes place in the provided scenario, but it does not match the 9:3:3:1 ratio. This is because the genetic linkage does not obey the principles of independent assortment, hence, fewer purple offspring are produced.
- As a result, mutations can cause Mendel laws to fail and have an effect on an organism's phenotypic features.

The correct answer is - B) the water quality of the stream.
By studying the fish populations and their well being, the watersheds, as well as the composition of the water, the scientists are trying to keep track of the situation of the quality of the water in the stream.
The fish populations, their activity, well being, are always a nice indicator about the water quality, as they live in it and are directly effected by any negative changes in the water quality.
The watersheds can also show a partial picture of the quality of the water in the streams, and that is because the water passes through them before entering the stream itself, so a clean and healthy watershed, often means good quality of the water.
The most relevant indicator of the quality of the water in the stream is still the testing of the water itself, where the water composition can be examined in detail thus to be determined its condition.
