Crossing over that results in genetic recombination in higher organisms occurs between |
|
a) |
Sister chromatids of bivalent |
b) |
Non-Sister chromatids of a bivalent |
c) |
Two daughter nuclei |
d) |
Two different bivalents |

Non-Sister chromatids of a bivalent |
c) |
Two daughter nuclei |
d) |
Two different bivalents |
(b) The process of crossing over takes place in pachytene stage of prophase-I of meiosis-I. In this process, some genes of two non-sister chromatids of a bivalent are exchanged. |
