Question 1
Solution
Mutation is
the spontaneously change in the sequence of nucleotides of its DNA which result
in formation of abnormal protein
I. Point mutation:
It is a type of
mutation which is result in change in one nucleotide or a nitrogenous base
sequence in DNA or protein which causes disorder.
2. Chromosomal abnormalities
These are caused
by the change to the number and structure of the chromosome It is due to
deletion. invasion and duplication of chromosome.
Benefits of mutation
The population
which undergoes mutation has grata chances of fun n al in the environment as
compare to common individual
Mutation provides thetas.:
material for the evolution and the form of genetic evolution.
Question2 Solution
Polyploidy is
principally duplication of entire genome of the monism. Polsploidy is very
important in the process of evolution, because this is produced the variation
in the next generation. The biased retention of genes tenoning WGD’s offers a
unique evolutionary potential to evolve key innovations and to increase
biological complexity in the long tems consequences of polyploidization are
complex and variable. and they differ greatly between systems and species, but
the process has often been considered to be an evolutionary end.
Alloploidy has to
be proof more significant than atdoploidy. because it has effect of
hybridization of DNA which leads to evolution. Allopolspbids contain two or
more distinct genomes and can arise through hybridization of two different
species concomitant with genome doubling.
