Mendelian Genetics · Botany

According to Mendel's Law of Segregation, what happens to the two alleles for a trait during gamete formation?

  1. They always stay together in the same gamete.
  2. They separate so that each gamete carries only one allele.
  3. They are destroyed and then recreated in the offspring cells.
  4. They fuse to form one new intermediate allele type.
Show answer and explanation

Correct answer: They separate so that each gamete carries only one allele.

The Law of Segregation states that the two alleles of a gene pair separate during meiosis. Consequently, each gamete receives only one member of the pair, ensuring the diploid number is restored upon fertilization.
