The science of heredity is known as Genetics. Here are the steps to understand it:

1. Definition: Genetics is the branch of biology that studies how traits are passed from parents to their offspring. This process is known as heredity.

2. Genes: The basic unit of heredity is the gene. Genes are segments of DNA located on chromosomes. They contain the instructions for the development and function of organisms.

3. DNA: DNA (Deoxyribonucleic Acid) is a molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of all known organisms and many viruses.

4. Chromosomes: Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of DNA.

5. Inheritance: Traits are inherited when genes are passed down from parents to offspring. This can happen through sexual reproduction (where each parent contributes half of the offspring's genes) or asexual reproduction (where all genes come from a single parent).

6. Genetic Variation: Variation in genes leads to variation in traits. This is why offspring are not identical to their parents or each other (unless they are identical twins).

7. Mutations: Changes in the DNA sequence of a gene are known as mutations. These can lead to new traits, and can be beneficial, harmful, or neutral.

8. Genetic Disorders: Some mutations can lead to genetic disorders, which are diseases caused by abnormalities in an individual's genome.

9. Evolution: Over time, genetic variation can lead to evolution, as certain traits become more common in a population.

10. Genetic Engineering: Scientists can now manipulate genes in a process known as genetic engineering. This can be used to produce desired traits in organisms.
