Gene is the molecular unit of the following:
Correct answer: C. Heredity
- A. DNA
- B. RNA
- C. Heredity
- D. Genotype
Explanation
Option C is correct since the gene is the molecular unit of heredity is a fact. Option A is incorrect since the gene is a short segment of DNA that codes for a polypeptide. A DNA molecule has many genes. Option B is incorrect since RNA has codons and not genes. Option D is incorrect since genes make up different DNA sequences called genotypes. So, it is not the molecular unit of genotype.

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.
