Question

(a) Can you consider cell division as a type of reproduction in unicellular organisms ? Give reason. 

(b) What is a clone ? Why do offsprings formed by asexual reproduction exhibit remarkable similarity ?

Answer 1

(a) Yes, because it leads to the formation two daughter cells.(b) The new organisms produced by one parent through asexual reproduction (which are genetically identical to the parent) are called clones. The offspring’s formed by asexual reproduction exhibit remarkably similarity because the replication of DNA in the cells is done by certain biochemical reactions which synthesise more of genetic material. When the DNA already present in the nucleus of the parent cell is replicated by making more DNA at the time of asexual reproduction then slight variations come in the two copies formed. Due to this the two DNA molecules formed will be similar but not identical.
