Which of the following is TRUE about sexual reproduction? Please choose the correct answer from the following choices, and then
Marina CMI [18]

Answer:

The correct answer is A. Sexual reproduction produces a greater variation in offspring.

Explanation:

  • B is wrong because in sexual reproduction there are two organisms involved who combine their DNA, therefore resulting in non-identical offsprings.
  • C is wrong because sexual reproduction requires the two organisms involved to exchange DNA's whereas asexual reproduction involves only one organism which only copies it's own DNA for reproduction.
  • D is wrong because there are no risks as genetic defects and no need to seek a mate or it is easier than sexual reproduction which results in lower risks for the parents in asexual reproduction.
  • E is wrong because asexual production is a more efficient procedure and results in a faster growing population because there is no need to search a mate.
  • The answer is A because in sexual reproduction, two different DNA's from both parents get combined resulting in more variation in offspring. In asexual reproduction, there is only one set of DNA which does not allow the gene's to mix, causing a less diverse offspring.
