a) |
Non-sister chromatids of the homologous chromosomes |
|
b) |
Sister chromatids of the homologous chromosome |
|
c) |
Chromatids of non-homologous chromosomes |
|
d) |
The genes those are completely linked |

(a) Crossing over is a process that produces new combination of genes by interchanging of segments between nonl-sister chromatids of homologous chromosomes. It occur between homologous chromosomes at four stranded stage during pachytene of prophase-I of meiosis-I. |
