Question

Why is the law of segregation also known as the Law of Purity of Gametes?

Options

• Because each gamete receives only one pure allele without any blending of both alleles from the parent

• Because gametes are physically cleaner than other cells

• Because gametes are produced in pure environments within the nucleus

• Because gametes cannot be contaminated by other genetic material

Answer 1

The law of segregation is called the Law of Purity of Gametes because gametes are pure with respect to each gene. During meiosis, the two alleles separate, and each gamete receives only one allele of each gene pair. This ensures the gamete carries a pure form of the gene, not a blend or mixture of both parental alleles.
