Q. Crossing over occurs between

NTA AbhyasNTA Abhyas 2020Principles of Inheritance and Variation

Solution:

In prophase I of meiosis, the replicated homologous pair of chromosomes come together in the process called synapsis, and sections of the chromosomes are exchanged. After crossing over, the resultant chromosomes are neither entirely maternal nor entirely paternal but contain genes from both parents. Synapsis and crossing over occur only in meiosis.
