Crossing over causes a recombination of genes and the eventual offspring to have a different genetic makeup then
either parent.
True
False

Respuesta :

Answer:

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.
