Mendel's laws are explained by:
Correct answer: B. Chromosome behaviour in meiosis
- A. Chromosome behaviour in mitosis
- B. Chromosome behaviour in meiosis
- C. Cytokinesis in mitosis and meiosis
- D. Mendel's laws have not been explained
Explanation
Mendel's laws (principles) of segregation and independent assortment are both explained by the physical behavior of chromosomes during meiosis. Random, independent assortment during metaphase I can be demonstrated by considering a cell with a set of two chromosomes (n = 2).

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.
