Which of the following correctly states Mendel’s law of segregation?

easy MCQ 1 mark Class 12 · Biology · Principles of Inheritance and Variation
  1. Alleles of different genes assort independently during gamete formation.
  2. Each individual possesses two alleles for a trait and these alleles separate during meiosis so that each gamete receives only one allele.
  3. Genes that are close together on the same chromosome are inherited together.
  4. Dominant alleles mask the effect of recessive alleles in heterozygotes.
Answer
Each individual possesses two alleles for a trait and these alleles separate during meiosis so that each gamete receives only one allele.

Step-by-step solution

  1. Identify the statement that describes separation of alleles of a single gene during gamete formation.
  2. Option B mentions that each individual has two alleles for a trait and they separate so each gamete gets one allele, which matches the law of segregation.
  3. Therefore option B is the correct choice.
Common mistake: Confusing it with the law of independent assortment

Concept tested: Mendel’s law of segregation
