Question 3

Mendelian Inheritance

The law of independent assortment states that

  1. A.genes for different traits are inherited together
  2. B.genes for different traits are inherited independently of each other
  3. C.homologous chromosomes do not separate during meiosis
  4. D.the dominant allele always masks the recessive allele
Show the answer and explanation

Answer: B (genes for different traits are inherited independently of each other)

Explanation

Mendel's second law says alleles of different genes separate into gametes independently, so one trait does not affect how another is inherited.
