Question

Homologus chromosome synapse length-wise. One of the homologus (of the pair) is of paternal origin and the other maternal origin. Explain

Answer 1

Synapsis is the pairing of two homologous chromosomes that occurs during meiosis. The lengthwise alignment of homologous chromosomes at the prophase stage of meiosis.

Sexually reproducing organisms have two sets of chromosomes, one set inherited from each parent. For these organisms to produce cells with a single set of chromosomes, the sets have to be separated such that the daughter cells have one copy of each chromosome that is of maternal origin and the other is of paternal origin.
