Explanation:
Leptotene
Leptotene shows first stage of prophase I in which each chromosome, having two sister chromatids, becomes visible as individualized chromosome. The closely associated sister chromatids can be visually distinguished from one another
Zygotene
Zygotene is second stage of prophase I, in which chromosomes line up with other chromosomes into homologous pairs of chromosomes. During zygotene, synapsis (pairing of chromosomes) occurs between homologous chromosomes that include formation of bivalent or tetravalent cheomosomes.
