When looking at a pedigree chart, it is important to understand the concepts of dominant and recessive genes that determine the traits of an individual. In genetics, dominant genes are those that are expressed over recessive genes when both are present. This means that if an individual inherits a dominant gene for a particular trait, that trait will be expressed in the individual. On the other hand, recessive genes are only expressed when an individual inherits two copies of the recessive gene.
Darken is a trait that can be inherited in a dominant or recessive manner. In the case of darkening of hair color, for example, if an individual inherits a dominant gene for dark hair, their hair color will be dark. However, if the individual inherits two copies of the recessive gene for light hair, their hair color will be light. This can be represented in a pedigree chart by shading in individuals who have the dark hair trait to indicate the dominant gene.

Interpreting Pedigree Charts
When analyzing a pedigree chart for traits such as darkening, it is important to look for patterns of inheritance. Dominant traits will often appear in every generation, while recessive traits may skip generations. By understanding the principles of dominant and recessive genes, you can accurately interpret pedigree charts and predict the likelihood of certain traits being passed down in a family.
Conclusion
In conclusion, pedigree charts are valuable tools for understanding the inheritance of traits such as darkening. By recognizing the patterns of dominant and recessive genes, you can decipher the genetic makeup of individuals in a family tree. By using pedigree charts, geneticists and researchers can track the inheritance of traits and better understand the complexities of genetic inheritance.
