Identify the process that is necessary for sexual reproduction. Also, explain why it is necessary and identify how this process increases genetic variation.

in Sexual reproduction two morphologically distinct types of specialized reproductive cells called gametes fuse together,. Each gamete contains half the number of chromosomes of normal cells and created by meosis and cause genetic variation

The process of sexual reproduction involves two parents contributing one gamete each. Gametes are produced by the process meiosis in which exchange of chromosomes happen causing genetic variation. Good luck!
