Question

which of the following statements best describes sexual reproduction?
a it produces genetically identical offspring
b it requires only one parent
c it results in greater genetic variation among offspring
d it occurs only in plants

Explanation:

• Option A: Asexual reproduction produces genetically identical offspring (clones). Sexual reproduction involves the combination of genetic material from two parents, so offspring are not genetically identical to either parent.
• Option B: Asexual reproduction requires only one parent. Sexual reproduction requires two parents (gametes from each).
• Option C: Sexual reproduction involves the fusion of gametes (sperm and egg in animals, pollen and ovule in plants). Each gamete has a unique combination of genes due to processes like meiosis (crossing - over and independent assortment). So, when gametes fuse, the offspring have a greater genetic variation compared to asexual reproduction.
• Option D: Sexual reproduction occurs in many organisms, not just plants. Animals, fungi, and some protists also reproduce sexually.

Answer:

C. It results in greater genetic variation among offspring
