In terms of X and Y chromosomes, explain why the sperm of the male determines the gender of the offspring.
Because the female egg contains only X chromosomes, and the sperm can contain either X or Y chromosomes, determining the gender.
Because the male sperm has no role in determining the gender of the offspring.
Because the female egg can contain either X or Y chromosomes.

In farming, many crops are produced by cloning. One method of cloning crops is to simply cut off a section of the plant, allow it to grow new roots, and then re-plant this cut section. One of the most commonly cloned food crops is the Cavendish banana.
Based on this information, which of the following statements is true?
Bananas from the cloned plant will taste different than bananas from the parent plant.
The cloned banana plants will not live as long as the parent plants.
Cloning banana plants is a very complex and expensive process.
Growing only cloned banana plants will limit the genetic variety on the farm.
