Inheritance Patterns of the Fruit Fly

The genetic pattern was studied using the Drosophila Drosophila or Drosophila genetic model. Only one fruit fly required for the 14 days from eggs to adults and 12 hours until breeding afterwards. Therefore, due to these factors, the fruit fly has enough time to mate and it is a suitable seed for research. I am studying the color of the eyes and the genetic pattern of feathers. Wild type flies have red eyes and intact feathers, but the mutant phenotype does not have brown eyes and feathers.

Drosophila melanogaster is a useful drosophila in biological research, especially genetics and developmental biology. (Manning, 1997) For the purpose of this experiment, Using Melanogaster, Mendelian inheritance patterns commonly found in genetic studies were investigated. The results of the final offspring indicate whether the trait of Drosophila is a product of an independent classification that is a Mendelian inheritance model or whether the non-Mendelian inheritance model is valid.

When people say "give priority to composition over inheritance", this is an abbreviation for "for combinations rather than inheritance" (the first mention to the "design pattern" of "4 GROUP"). Class inheritance has many flaws and causes many problems, so this is common sense of object-oriented design. When people talk about class inheritance, people usually ignore the class of words. It seems all inheritance is bad - but it is not so. `BassAmp` is inherited from` GuitarAmp`, 'ChannelStrip` is inherited from' BassAmp` and `GuitarAmp`. This is an example of an object-oriented design error. The channel strip is not actually a guitar amp, actually it does not require a cabinet at all. A better option is to create a new base class for inheritance of amplifiers and channel strips, but this is also limiting.

In JavaScript, class inheritance depends on very rich and flexible prototype inheritance embedded in the language long ago, but when using class inheritance - ES6 + built on the prototype with `class` inheritance Even I will not use it. Object-oriented full power and flexibility of the prototype. In fact, you have pulled yourself into the corner and have chosen all class inheritance problems.

Class inheritance is just a complex object construct. All classes generate composite objects, but not all compound objects are generated by class or class inheritance. "Object configuration support in class inheritance" means forming complex objects from widget components rather than inheriting all properties from ancestors in the class hierarchy. Inevitable repetition problem: Because of the inflexible hierarchy, new use cases are usually implemented by copying rather than by extension, and similar classes will unexpectedly branch. Once replication is started, it is unknown which class needs to start a new class or why.
