<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>
Mutations are the changes produced in the nucleotide sequence of the genome.
There are four main types of mutations
Substitution
Insertion
Deletion
Duplication.
<h2>_____________________________________</h2><h3>DELETION:</h3>A small segment of chromosome mat be missing. This condition is known as deletion.
For example, Normal chromosome has A B C D E F G. If deletion mutation occurs then mutated chromosome has A D E F G and B C got deleted.
<h2>_____________________________________</h2><h3>DUPLICATION:</h3>In this condition, a part of chromosome present in exec ess to the normal chromosome.
For example, Normal Chromosome has A B C D E F G. If duplication mutation occurs, then mutated chromosome had A B C B C D E F G and B C is duplicated.
<h2>_____________________________________</h2><h3>SUBSTITUTION MUTATION:</h3>Substitution is a type of mutation where one base pair is replaced by a different base pair.
For example, in the sequence CAAGT, if C replaces G, it is a substitution mutation.
<h3>INSERTION MUTATION:</h3>In genetics, an insertion is the addition of one or more nucleotide base pairs into a DNA sequence.
For example, in the sequence CAAGT, if extra base G gets inserted after C, the new sequence would be CGAAGT.
<h2>_____________________________________</h2>Both substitution and insertion mutations change the position of nucleotide thus, the type of amino acid.

Explanation:
<em>The probability of producing plants with white axial flowers would be 1/16.</em>
From the illustration, All F1 individuals had red, axial flowers. It thus means that red and axial genes are dominant over white and terminal genes in the pea plant.
Let us assume that the allele for flower color is A (red) and a (white); and the allele for flower location is B (axial) and b (terminal).
Pure-breeding red, axial flower = AABB
Pure breeding white, terminal flower = aabb
AABB x aabb
F1 genotype = AaBb - all red and axial
At F2:
AaBb x AaBb
Progeny
<em>9 A_B_ red/axial</em>
<em>3 A_bb red/terminal</em>
<em>3 aaB_ white/axial</em>
<em>1 aabb - white/terminal</em>
Hence, the probability of producing plants with white axial flowers in the F2 generation is 1/16.
