Which reproductive method involves the combination of genetic material from two parents?

• A. Asexual reproduction
• B. Sexual reproduction
• C. Binary fission
• D. Implantation

Answer: (B)

The method that involves the combination of genetic material from two parents is sexual reproduction. In this process, gametes, which are specialized reproductive cells (sperm and eggs, for example), are produced by each parent. When these gametes unite during fertilization, they create a zygote that contains a mix of genetic information from both parents. This genetic recombination leads to offspring that are genetically distinct from their parents, contributing to greater diversity within a population. In contrast, asexual reproduction refers to a process where a single organism generates offspring that are genetically identical to itself, with no exchange of genetic material. Binary fission is a specific type of asexual reproduction commonly found in prokaryotic organisms, such as bacteria, where a single cell divides into two identical cells. Implantation is a stage in reproduction where a fertilized egg attaches to the uterine wall, but it does not involve the combination of genetic material itself. Therefore, sexual reproduction is the correct answer, as it emphasizes the significant role of genetic exchange between two individuals.
