Answer:
A. Haploid cells formed by meiosis combine to produce a diploid cell.
Step-by-step explanation:
During the process of sexual reproduction, new organisms are formed through the combination of genetic material of two organisms. Sex cells (gametes) from two parents combine, leading to the formation of a new, genetically distinct individual.
This is mediated by meiosis and fertilization
- Meiosis: The number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.
- Fertilization: The fusion of haploid (n) gametes occurs, and the original chromosome number (2n) is restored; the zygote then undergoes mitotic division to form an organism.
