Question

Which mutation is beneficial for evolution?

Answer 1

Mutation:

1. When the DNA's nucleotide sequence is changed and a new sequence is transmitted to the progeny, this is known as a gene mutation.
2. One or more nucleotides may be substituted for others, or one or more pairs of nucleotides may be added or removed.

Evolution:

1. Evolution is the shift through time in the inherited traits of biological populations.
2. These traits are manifestations of genes that are transferred from parents to children during reproduction.

Beneficial aspects of the mutations:

1. The biological activity of a protein may or may not be significantly impacted by a nucleotide change in the DNA that causes an amino acid substitution in the associated protein.
2. The adaptability of the organism could be enhanced by a new mutation.
3. The likelihood of such an occurrence increases as organisms invade new areas or when environmental changes presents a population with fresh difficulties.
4. In these situations, a population's established adaptability is subpar, which increases the possibility that new mutations will be more adaptable.
5. The environment has an impact on how mutations manifest themselves.
6. In Scandinavia, where sunlight intensity is low and light skin promotes vitamin D production, increased melanin pigmentation is not favorable.
7. In tropical Africa, where dark skin protects people from the Sun's UV radiation, increased melanin pigmentation may be helpful.
8. There are a few more examples of mutations beneficial for evolution:

• HIV resistance
• Lactose tolerance
• Trichromatic vision.
