Explanation / Answer

Option 1st and 4th are correct. In case of independent assortment of chromosomes, one of the chromosome is completely substituted by parental chromosome and thus, separation of mutation occurs with other mutations in other chromosomes while in case of crossing over a particullar segment of a chromosome is exchanged with parental chromosome and thus separation of mutation occurs from same chromosome.
