Q.“Gametes are never hybrid”. This statement is associated with the :

'Gametes are never hybrid' describes the clean separation of paired alleles into different gametes -- the Law of Segregation.

Working

Mendel's three principles, applied to a monohybrid cross (a single gene with two alleles, e.g., T = tall, t = dwarf, in a heterozygous Tt plant):

• Law of Dominance: in the heterozygote Tt, only the dominant allele T is expressed in the phenotype (the plant looks tall), while t remains masked.
• Law of Segregation: during gamete (meiosis) formation, the paired alleles T and t, which lie on homologous chromosomes, separate from each other cleanly, so that each individual gamete receives only one allele -- either T or t, never both together in the same gamete. In other words, a gamete is always 'pure' for a given gene, never a hybrid combination of both alleles; this is why Mendel called it the Law of Purity of Gametes. …
