What methods are used by geneticists to study the laws of heredity and variability.

The main method of genetics is hybridological. This is the crossing of certain organisms and the analysis of their offspring. This method was used by G. Mendel.
Genealogical – the study of pedigrees. Allows you to determine the patterns of inheritance of characters.
Gemini – a comparison of identical twins, allows you to study modification variability (to determine the effect of genotype and environment on the development of the child).
Cytogenetic – the study under a microscope of the chromosome set – the number of chromosomes, their structural features. Detects chromosomal diseases.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
