Answer
DNA mutation introduces new alleles into a population, leading to variations in offspring. Gamete formation, through processes like meiosis, ensures that offspring inherit different combinations of alleles, contributing further to genetic diversity.

Answer
While cell differentiation is essential for the specialization of cells, it does not contribute to genetic variation in offspring. Only gamete formation contributes to genetic variation.

Answer
Though DNA mutation contributes to genetic variation, polypeptide production is the expression of genes but does not directly introduce variation in offspring.

Answer
Neither cell differentiation nor polypeptide production results in genetic variation, as these processes do not involve the introduction of new alleles or gene combinations.
