Which of the following statements correctly describes Mendel's Law of Segregation?

easy MCQ 1 mark Class 12 · Biology · Principles of Inheritance and Variation
  1. Alleles of a gene separate during meiosis so that each gamete receives one allele.
  2. Genes on different chromosomes assort independently.
  3. Dominant allele masks recessive allele in heterozygote.
  4. Crossing over occurs between homologous chromosomes.
Answer
Alleles of a gene separate during meiosis so that each gamete receives one allele.

The correct answer is Alleles of a gene separate during meiosis so that each gamete receives one allele. — Therefore, option 1 is the correct answer.

Step-by-step solution

  1. Identify the definition of the law of segregation: it states that the two alleles of a gene separate during gamete formation.
  2. Examine each option and see which one matches this definition.
  3. Option 1 states that alleles separate during meiosis and each gamete gets one allele – this is exactly the law of segregation.
  4. The other options describe independent assortment, dominance, or crossing over, which are different concepts.
  5. Therefore, option 1 is the correct answer.
Common mistake: Confusing the law of segregation with the law of independent assortment.

Concept tested: Law of Segregation
