How does the law of dominance account for the variation that occurs during gamete famrmation?

The law of dominance states that in a heterozygous genotype, one allele can mask the expression of another, leading to a dominant phenotype. During gamete formation, alleles segregate independently due to meiOSis, resulting in gametes that can carry either the dominant or recessive allele. This segregation contributes to genetic variation, as offspring can inherit different combinations of alleles from each parent, leading to diverse phenotypic expressions even when the dominant allele is present. Thus, while dominance influences phenotype, the independent assortment of alleles during gamete formation fosters genetic diversity.
