Answer:
This question lacks options, however, it can be answered based on general understanding of the topic
The answer is SUBSTITUTION MUTATION
Explanation:
A mutation is any change that occurs in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. One type of mutation is SUBSTITUTION MUTATION, which is a mutation in which one or more nucleotide base is replaced by another in the sequence.
Nucleotide bases are read in a group of three called CODON. Each of these codons specify amino acid. Hence, if the nucleotide base sequence is altered during mutation, the amino acid sequence is altered likewise. In this case where the original amino acid sequence is: Met-Ala-Gln-Arg-Glu-Leu, the mutation affected the nucleotide bases coding for Arginine (Arg), hence changing it to Glycine (Gly).
This means that a base substitution mutation occured, replacing the amino acid Arginine with Glycine in the mutated sequence.
The environment provides the selective pressure in natural selection. Artificial Selection is a type of choice in which people effectively pick which characteristics ought to be passed onto posterity. People have utilized particular rearing some time before Darwin's Postulates and the disclosure of hereditary qualities. It is the rearing of plants and creatures to deliver attractive qualities. Living beings with the coveted characteristics, for example, size or taste, are misleadingly mated or cross-pollinated with creatures with comparable wanted attributes.
Any physical characteristic can be passed on from generation to generation. However, some characteristics are influenced by the environment as well as having a genetic predisposition for that specific trait.
