Genetic shuffling in sexual reproduction, also called gene recombination occurs during meiosis and also when different organisms exchange genetic material such as in bacteria.
answer:
earth's average temperature would be near 0°F (or -18°C)
explanation:
greenhouse gases in the air, mainly carbon dioxide, methane, and water vapor, trap radiation from the Sun and act as a thermal blanket around the planet. without the greenhouse effect, earth would have an average temperature of -18 °C and be covered in ice. life as we know it would not be able to survive.
good luck :)
hopefully this helps
have a great day !!
