Answer:
Mutation, fertilization, meiosis are different mechanisms by which changes can occur in the genome.
Explanation:
There are several process which is responsible for causing change in the genome of the species which results in the evolution of that species. Some of these processes are:
1. Mutation: In mutation, some nucleotide sequences get change and this change can occur due to frameshift, addition, deletion or any other process. This change in nucleotide can be seen in phenotype and helps in the evolution of the species.
2. Fertilization: During fertilization mixing of the genome of two individual takes place which results in producing a genetically distinct offspring which contains variation. So as the offspring is genetically different it can contain new alleles that can help the individual to survive in the changing environment.
For divergent boundary: when the crust of the earth fractures it allows magma to reach the surface. For convergent boundary: When one of the converging plates move underneath the other, a process also known as subduction; the new magma rises and can erupt to form volcanos. For the Hotspot: magma pushes through cracks in the crust to form volcanos. Hope this helps!!
Answer: I say the answer is "an identical environment" because, If the organism is genetically identical then that means that not much would have to change as in the organisms features.
