To draw:
The chromatids that would result from two-strand double cross over occurring between the chromosome in Fig.8.12: “In an individual heterozygous for a paracentric inversion, the chromosomes form an inversion loop during pairing in prophase I”, one crossover is between C and D and other crossover between D and E.
Introduction:
The crossing over is the pairing of the homologous chromosomes in the prophase I of meiosis. During this process, some of the parts of the chromosomes are exchanged, which lead to the generation of recombinant strands. The crossing over results in production of the recombinants and parental type strands. However, the frequency of recombination depends on the distance between the two genes.
