- Heredity is the passing on of traits from parents to their offspring.
- These changes are passed on because of DNA and crossing over of genes.
- The traits that an organism possess are present because of their DNA. Their DNA has the information to express those traits/characterstics.
- In human beings, there are 46 chromosomes or 23 pairs of chromosomes, one from each parent.
- During gamete formation, the gamete takes one chromosome from each pair.
- When two such gametes having a single set of genes combine together, they restore the normal diploid number of chromosomes in the progeny.
- This is the mechanism of inheritance of traits.
