The answer is a pedigree chart.
Pedigree charts are used to explain the occurrence of particular genes from one generation to the next. It gives enough information about family disease history. They are used in families to find out the probability of inheriting some disease.

The endocrine system is the system that releases hormones. It is involved in developing the reproductive characteristic and maintains the condition for reproduction.
The endocrine system is involved in the coordination and control of reproduction, growth, metabolic process, etc. It is involved in the production of the male and female gametes that fuse during the reproduction process.
If the gametes fuse and form the zygote then the endocrine system release hormones that maintain the environment required for the embryo to grow and develop in the female body.
Therefore, the endocrine system plays an important role in reproduction.
