Question
Which of the following is referred to as the exchange of genetic material between homologous chromosomes?
- Crossing over
- Mutation
- Reproduction
- Independent assortment
Hint:
The process occurs during prophase 1 of meiosis.
The correct answer is: Crossing over
- Crossing over is referred to as the exchange of genetic material between homologous chromosomes.
- Homologous chromosomes have the same length and same genes at the specific locus.
- Crossing over occurs during pachytene stage of prophase 1 of meiosis.
- During the process, the homologous chromosomes attach to one another and exchange different segments of chromosome resulting in the formation of a recombinant chromosome.
