Answer:
A gene mutation can be described as errors in the nucleotide sequence of a gene due to errors in the DNA replication process or due to any mutagen. On the other hand, a chromosomal mutation can be described as a change in the structure of a DNA or changes in the number of chromosomes.
A gene mutation occurs in a single gene whereas a chromosomal mutation will affect many genes. Hence, gene mutations will be comparatively less lethal than chromosomal mutations.
Example of gene mutation: Sickle cell anemia
Example of chromosomal mutation: Down's Syndrome
An exotic species is not native to the environment that it is introduced to. Exotic species rarely cause environmental harm. Invaasive species, however, are introduced to a new environment and tend to cause harm in some form, whether it is detrimental in an economic or environmental way.
<span>They are the same genes, but have slightly different nucelotide sequences. These might or might not be mutations, but they still allow for the characteristic to be coded and expressed. This shows the diversity in the range of ways that a gene can be expressed.</span>
