Why are offspring of the same parents not exactly identical?
Answer and explanation
Correct answer: Because different combinations of genes form in sexual reproduction
The governing concept is variation produced during sexual reproduction. Each child receives genetic material from both parents, but meiosis and the random fusion of gametes create a different combination of alleles in each offspring. Small mutations and environmental influences may also contribute to differences. Genes are not destroyed, parents do transmit traits, and environment alone does not determine everything; therefore option A is correct.
