It can be genetics, but also offspring learn from their parents. The more complex the organism, the greater the role of learning. Thus the characteristics of higher level organisms are developed from a complex interaction between genetics and life experiences. One of the main experiences is the parents "modeling" behavior for the offspring to imitate.
Rather than confusing the issue, I hope this helps a little more. Thanks for asking.
The study of characteristics from one organism to its offspring is called "genetics." Genetics is a field of biology that focuses on understanding how traits are passed from parents to their offspring. These traits can be physical characteristics, such as eye color or height, as well as genetic disorders or predispositions to certain diseases. Genetic information is contained in molecules called genes, which are located on structures called chromosomes. Inherited traits are determined by variations in genes, and the study of genetics helps us understand how these variations are transmitted from one generation to the next. To gain a deeper understanding of genetics, scientists use several tools and techniques, including pedigree analysis, DNA sequencing, and genetic engineering.
