Question

During gamete formation in a heterozygous organism (Tt), what is the result regarding allele distribution?

विकल्प

• Each gamete receives both the T and t alleles together

• Each gamete receives only ONE allele and is pure, never a blend of both

• Each gamete randomly receives either one, two, or no alleles

• Gametes receive a blended version of both alleles called Tt

Answer 1

The law of segregation, also called the Law of Purity of Gametes, states that during gamete formation, the two alleles of a gene pair separate from each other. Each gamete receives only ONE allele, making it pure and never a blend of both alleles. This ensures that gametes are haploid with respect to each gene.
