Answer
Crossing over is the phenomenon in which exchange of chromtids occur between non sister chromatids and result into recombinant chromatids, which is an important tool for evolution and bring about genetic changes in offsprings as compare to their parents.
No crossing over
If no crossing over occurs, it means no exchange of chromatids between non sister chromatids of homologous chromosomes, then no recombinant chromatids will be formed.
Result
At the end of meiosis II, when four haploid cells are formed, all these cell will contain similar chromosomes as present in parent. Thus chromosomes are non recombinant because of no crossing over.
