The different forms a gene may have for a trait are called alleles. These are variations of a gene present on homologous chromosomes. A trait in an individual is determined by the two alleles inherited from their parents.
The different forms a gene may have for a trait are called alleles. These are variations of a gene that occur at the same relative locations on homologous chromosomes. For example, in a diploid organism where a single gene controls a characteristic, there can be two genetic copies, or alleles, that may or may not encode the same version of that characteristic.
A slight change in the sequence of nucleotides within a gene can result in different alleles that code for different traits. For instance, the different alleles for the gene that determines blood type in humans are sequence A, sequence B, and sequence O. The blood type is a trait determined by the two alleles that are inherited from the parents.
It's important to note that while an individual can only have two alleles for a given gene, it's common in a natural population to encounter more than two alleles for any given gene, a phenomenon referred to as multiple alleles.

C) A large amount of iron zinc and lead mine he had poison the water supply

It just occurred to have been sitting at the top of 21000 tons of toxic industrial waste, which had been buried underground in the 1940s and 50s by a local company.
The families living in the chemicals were not familiar that they were being encountered with poisonous chemicals, nor were they aware of the chemical wastes being dumped into the soil, rivers, and air. The toxic wastes influenced the lives and damaged the environment.
The correct answer is option B.
Love canal is located near the Niagara Falls in the year 1978. It is sitting over the 21000 tons of toxic industrial waste, that has on the whole buried underground in the year 1940s by the support of some local company side.
