Mendel's laws are explained by:
Correct answer: C. Chromosomes behaviour in meiosis
- A. Chromosomes behaviour in mitosis
- B. Cytokinesis in mitosis and meiosis
- C. Chromosomes behaviour in meiosis
- D. Mendel's laws have not ben explained
Explanation
Correct option: C Mendel's laws, which describe patterns of inheritance, can be explained by the behavior of chromosomes during meiosis. Meiosis is the cell division process that produces gametes (sex cells), and it involves the recombination and segregation of chromosomes. The segregation of alleles during meiosis corresponds to Mendel's Law of Segregation, while the independent assortment of chromosomes corresponds to Mendel's Law of Independent Assortment. Therefore, option C, chromosomes behavior in meiosis, provides an explanation for Mendel's laws.

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.
