i) -crossing over
ii) -this is the process by which the two chromosomes of a homologous pair exchange equal segments with eachother
iii) -Though these terms are closely related and very confusing to each other, there are still a lot of things that differs each one of them. A long and continuous strand of DNA is what Chromosomes are but when two chromatids are united together with a centromere, it produces one chromosome. Chromosomes, as mentioned above, are vectors of heredity or the ones that carries the genes of one organism to the other like the physical appearance and different characteristics while Chromatids are the ones who made possible the replication of these cells.
These DNA terms are really confusing if not studied deeply due to the fact that they are interconnected with other. To put it in a picture wherein every one can understand, chromosomes when viewed in a microscope is like an X shape. Divide the X by half and it would result into > and <. A single > or < is what you call a chromatid. The center point of contact is the centromere and the whole X is the chromosome.
