Question

which three processes are methods of genetic recombination?
natural selection, crossing over, and independent assortment
crossing over, independent assortment, and fertilization
independent assortment, fertilization, and natural selection
fertilization, natural selection, and crossing over

Explanation:

• Crossing over: Occurs during meiosis I, where homologous chromosomes exchange genetic material.
• Independent assortment: During meiosis I, homologous chromosome pairs align randomly at the metaphase plate, leading to different combinations of chromosomes in gametes.
• Fertilization: Combines genetic material from two gametes (sperm and egg), creating a new genetic combination in the zygote.
• Natural selection is not a method of genetic recombination. It is a process by which organisms better adapted to their environment tend to survive and reproduce more successfully.

Answer:

crossing over, independent assortment, and fertilization
