Since the early twentieth century, inheritance was seen as the inheritance of genes. Concurrent with the acceptance of the genetic theory of inheritance was the rejection of the idea that the cytoplasm of the oocyte could also play a role in inheritance and a corresponding devaluation of embryology as a discipline critical for understanding human development. Development, and variation in devel...

Inheritance is one of the main concepts of object-oriented technology. It is claimed that the use of inheritance improves productivity and decreases development time. John Daly et al. reported on two experiments evaluating the effects of inheritance depth on program maintenance. They found that maintenance was performed significantly quicker for software using three levels of inheritance, compa...

Inheritance is one of the key concepts in object-oriented programming (OOP). However, the usefulness of inheritance in concurrent OOP is greatly reduced by the inheritance anomalies. These anomalies have been subjected to intense research, but they are still only vaguely de ned and often misunderstood. In this paper we show that concurrency is not the real cause of inheritance anomalies. We for...

The practice of dividing pre-death inheritance in Pehserut Village is an phenomenon that follows Javanese customary law by prioritizing several aspects mutual benefit, but the distribution model occurs community does not get legality classical Fiqh or Indonesian positive law. Moreover, Islamic which incidentally oriented to opinion Sunni scholars on fiqh issues, distinguishes between terms gran...

This thesis develops a semantic model of inheritance and investigates its applications for the analysis and design of programming languages. Inheritance is a mechanism for incremental programming in the presence of self-reference. This interpretation of inheritance is formalized using traditional techniques of fixed-point theory, resulting in a compositional model of inheritance that is directl...

There is a natural partial ordering of defaults in inheritance systems that resolves ambiguities in an intuitive way. This is not the shortest-path ordering used by most existing inheritance reasoners. The flaws of the shortest-path ordering become apparent when we consider multiple inheritance. We define the correct partial ordering to use in inheritance and show how it applies to semantic net...

The need to inherit those membranes that arise from the ER is much less clear. As an example, the integral *Imperial Cancer Research Fund Cell Biology Laboratory membrane proteins and lipids of the Golgi apparatus are derived entirely from the ER. If a daughter did not 44 Lincoln's Inn Fields London WC2A 3PX inherit a copy of the Golgi apparatus, it should be able to synthesize one de novo. Sev...

Mitochondria contain their own DNA (mtDNA), which codes for 13 proteins (all subunits of the respiratory chain complexes), 22 tRNAs and 2 rRNAs. Several mtDNA point mutations as well as deletions have been shown to be causative in well-defined mitochondrial disorders. A mixture of mutated and wild type mtDNA (heteroplasmy) is found in most of these disorders. Inheritance of mtDNA is maternal, a...

Inheritance is the vital feature of any object oriented software which provides reuse of exiting classes for designing new classes. Higher reuse provides higher productivity and greater quality. Inheritance hierarchy is one of the very important artifacts targeted for measurement of reuse and reusability. Reuse through inheritance hierarchy can be measured from two dimensionsDepth and Breadth. ...

Inheritance is the main principle in object-oriented design methods to support structuring and reuse of object behaviour descriptions. Most proposals restrict the (formal) use of inheritance to method interfaces and method eeect speciications. We propose to extend the inheritance relation to cover whole object life cycles, i.e. to long term object behaviour. After sketching the basic idea of in...
