Types of dominance, multiple alleles, sex linked inheritance, polygenic inheritance and maternal inheritance.
Inheritance refers to the concept by which the features from one class can be extended/made available in other classes. Java supports 3 forms of inheritance * Single Inheritance * Multiple Inheritance * Multilevel Inheritance (Can be implemented using interfaces)
Polygenic inheritance
Multiple gene inheritance. Sree
"polygenic inheritance"- the inheritance of quantitative traits, traits which are influenced by multiple genes. Polygenic inheritance shows how multiple genes in combination with a person's environment can influence someone's phenotype, or physical appearance. A wide range is produced because the gene combinations are vast.
Java does not support multiple inheritance
Single Inheritance Multiple Inheritance Multilevel Inheritance
Types of dominance, multiple alleles, sex linked inheritance, polygenic inheritance and maternal inheritance.
When more than two alleles are involved in the inheritance of a trait, it is called polygenic inheritance. Many quantitative characters have polygenic inheritance. Inheritance of blood groups is an example of polygenic inheritance in human being.When more than two alleles are involved in the inheritance of a trait, it is called polygenic inheritance.

Java does not support multiple inheritance. It is done with the help of interfaces in java. a class can implement n number of interfaces, thus showing multiple inheritance. but a class cannot extend multiple classes in java.
Java does not allow the multiple inheritance of concrete classes, though it does allow a "hybrid" inheritance of one concrete class and multiple interfaces.
Java does not support direct multiple inheritance. You can implement partial multiple inheritance using interfaces. ex: public class ExMultInherit implements interface1, interface2, interface 3 { ... .... ...... }
There are no drawbacks to multiple inheritance if multiple inheritance is precisely what is required to achieve your goal. If there are any drawbacks then it is only because of poor design, not multiple inheritance itself. For instance, when designing classes to simulate vehicles, an amphibious vehicle would inherit the properties of both an off-road vehicle and a marine vehicle, therefore multiple inheritance would be an appropriate usage.
C is not object-oriented -- you can't even use single inheritance let alone multiple inheritance.
Java does not support direct multiple Inheritance. Harder to implement, not every language support it: C++ does, Java does not.
Actually, java does not support multiple inheritance. You can achieve partial multiple inheritance using interfaces but java is not like C or C++ where you can do direct multiple inheritance. However, you can achieve partial multiple inheritance with the help of interfaces. Ex: public class FerrariF12011 extends Ferrari implements Car, Automobile {…} And this is under the assumption that Car and Automobile are interfaces. Here if you see, though you don't inherit concrete code from the Car or the Automobile interface, you do inherit skeleton methods that determine the way your class eventually behaves and hence this can be considered partial Multiple Inheritance.
There are only two types of inheritance to begin with: single inheritance and multiple inheritance. Since they are mutually exclusive there is no such thing as hybrid inheritance.
