During which stage of meiosis does crossing over occur?

prophase I of meiosis Click to see full answer. In this regard, during which stage of meiosis does crossing over occur quizlet? prophase I Similarly, why is crossing over in meiosis important? Crossing over is essential for the normal segregation of chromosomes during meiosis. Crossing over also accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical. Beside this, what is crossing over and when does it occur in meiosis? Crossing over (genetic recombination) is the process where homologous chromosomes pair up with each other and exchange different segments of genetic material to form recombinant chromosomes. It occurs between prophase 1 and metaphase 1 of meiosis.What is the process of crossing over?crossing over, process in genetics by which the two chromosomes of a homologous pair exchange equal segments with each other. Crossing over occurs in the first division of meiosis . At that stage each chromosome has replicated into two strands called sister chromatids.
