If you are told that the allele that produces a widow's peak differs by only a single nucleotide that changes a single amino acid from the allele that does not produce a widow's peak, which type of mutation occurred between these alleles?

Select one:

a. silent mutation
b. rearrangement
c. deletion
d. missense mutation
e. insertion
f. nonsense mutation

The correct answer is option d, that is, missense mutation.

Explanation:

A missense mutation is a kind of nonsynonymous substitution. In this form of mutation, a modification in a solitary nucleotide takes place that results in the formation of a codon that codes for a distinct amino acid. In this mutation, a change in DNA nucleotide results in the administration of a different amino acid within a protein. Though the mutation is not that harmful, however, it can slow down the working of a specific protein.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
