Mendel's law of independent assortment can be explained by:
Correct answer: B. Behaviour of chromosomes in meiosis
- A. Behaviour of chromosomes in mitosis
- B. Behaviour of chromosomes in meiosis
- C. Gene behaviour in mitosis
- D. Both a and b
Explanation
Mendel's law of independent assortment states that different genes are sorted independently of each other during gamete formation. This means that the alleles of one gene do not influence the alleles of another gene.This law can be explained by the behavior of chromosomes during meiosis, specifically:1. Chromosomes pair up and exchange genetic material during crossing over2. Homologous chromosomes separate and move to opposite poles during anaphase I3. Sister chromatids separate and move to opposite poles during anaphase IIThis results in a random combination of chromosomes and genes in the gametes, ensuring independent assortment.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
