Question

Which of the following is not the
characteristic of asymmetric karyotype?

• A. large differences between smallest and largest chromosomes
• B. few metacentric chromosomes
• C. has no evolutionary significance
• D. advanced type

Answer 1

The correct option is C has no evolutionary significance

An asymmetric karyotype is one having large differences between smallest and largest chromosome of the set and having fewer metacentric chromosomes. It is considered to be a relatively advanced feature when compared with symmetric karyotypes. It is evolutionarily significant since there are several factors which generate variation in the karyotype during evolution.

So, the correct option is 'has no evolutionary significance'.
