In sexual reproduction, if each chromosome in a pair has the same genes, how is genetic variety possible?
ruslelena [56]

Answer:

The same genes or slightly different versions of the same gene can be found on each chromosome in a pair. They form a line and split off bits of themselves, which they barter with one another. In sexual reproduction, crossing over is the first method that genes are shuffled to develop genetic variation.
