Crossing over causes a recombination of genes and the eventual offspring to have a different genetic makeup then

either parent.

True

False

True.

Explanation:

Recombination of genes on the same chromosome is accomplished by crossing over, a process by which parts of homologous chromosome are interchanged. Crossing over is important for evolution because it generates variation in a species. Crossing over occurs at pachytene after the synapsis of the homologous chromosomes in prophase I of meiosis. Crossing over involves the breakage of each of two homologous chromosome and exchange of parts. Since parts of chromosome combine the offspring develops a different genetic makeup from the parents. Thus, Crossing over causes a recombination of genes and the eventual offspring to have a different genetic makeup then either parent.
