Concept:Sexual reproduction involves the fusion of male and female gametes from two parents to produce genetically varied offspring.
Explanation:Each parent produces haploid gametes such as sperm and egg.
During fertilization, these gametes fuse together to form a zygote.
The offspring inherit a mixture of genetic material from both parents.
This mixing creates genetic variation among the offspring.
Option B describes asexual reproduction, where offspring are identical to one parent.
Option C also refers to asexual reproduction, as no gametes are involved.
Option D is false because sexual reproduction definitely requires gamete formation and fusion.
Therefore, only Option A correctly describes sexual reproduction.
Answer:It involves the fusion of gametes from two parents, resulting in offspring with genetic variation (Option A).
