Correct answer: C. Nuclei of two specialized cells fuse together
- A. All types of organisms reproduce
- B. Many cells of one type fuse with a single cell of another type
- C. Nuclei of two specialized cells fuse together
- D. Parents produce genetically identical offspring
Explanation
Sexual reproduction occurs when the sperm from the male parent fertilizes an egg from the female parent, producing an offspring that is genetically different from both parents. In most species the genetic information is carried on chromosomes in the nucleus of reproductive cells called gametes(sperm and ova), which then fuse to form a diploid zygote.
