Answer:
Not necessary but sufficient
Explanation:
All the three predictors of cancer can be causative agents for the disease. Hence, if any of these are present, it may trigger cancerous cell production. The mechanism of causing cancer in all these elements is different and they does not complement each other. Benzene is a toxic chemical which upon continuous inhalation cause cancer. Genetic mutation may serve as a hereditary risk factor to abnormal and diseased cell production. Similarly, high radiation dose may also trigger rapid production of cancerous cells.

It involves an exchange of carbon as Plants and Animals remove carbon from the atmosphere by various activities. At the same time, they add carbon back to the atmosphere by various activities.
When a purple flower with a genotype PP is crossed with a white flower that has a genotype of pp. The phenotype of the offspring would be Purple (Pp).
<h3>What is Genotype?</h3>
Genotype may be defined as the ultimate combination of the alleles of those genes which are selected for specific studies.
The phenotype of the offspring would be Purple (Pp). This is because the allele of the purple phenotype is dominant over the allele of the white phenotype. That is P > p.
The Punnett Square may be represented below:
Therefore, it is well described above.
