What does “Law of segregation” actually mean in Principles of Inheritance and Variation, and why does it matter for NEET?
the two alleles of a gene separate during gamete formation, so each gamete carries only one of them.
In simple words: the two alleles of a gene separate during gamete formation, so each gamete carries only one of them. Getting Law of segregation clear matters because NEET questions on Principles of Inheritance and Variation usually test this idea directly, not just a formula you memorised.
Key point
Law of segregation
Common mistake
thinking both alleles of a gene can enter the same gamete.
Memory tip
gametes are always pure -- exactly one allele of each gene per gamete.
