Drosophila
Reproduction among various species is a key part of studying genetic of inheritance between individual species and their offspring. Genetics have discovered the structures that can simply be studied. The model that is being studied is in a domestic pest that may be found throughout decaying food. The topic that is being examined is the Drosophila. When Drosophila is prepared for mating or hatching, they have a full lifecycle of about 20 days, thus are the models for relating sex-linked inheritance. Obviously it is not the breeding ways of the Drosophila that is being examined in this experiment, but the developing offspring, and their phenotypes. The phenotype is based on the wing shape and the eye color, which is resulted by grouping of genes

The Central Dogma of Molecular Biology describes that Deoxyribonucleic Acid (DNA) is the important structure of an organism that created into DNA, is a sum of amino acids that code for important proteins, and that is why the genes are the code that selects the amino acids sequences that builds up the essential proteins in the body. During sexual reproduction these genes found on coiled bands of DNA that are passed down randomly the mother and father. This genetic evidence differs not only in the mixture and comparison of a gene, known as an allele, but also it is found on the mixture of sex chromosomes creating either male or female species. Sex-linked genes differ based on the chromosomes given: males given an X Y chromosome while a female given an X chromosome from the mother and the other XX chromosome. A gene can be sex-linked if two X chromosomes in a female or a Y chromosome in a male is present. Females obtain two copies of the X-linked gene thus a female body can have a greater amount of gene dosage and protein. In series for sex-linked inheritance to happen it must be determined that the gene is associated to the presence of an X or Y chromosome. If this does not happen then the gene is shared by both males and female and it is considered to be an autosomal gene. In a rearrangement of genetic material, an autosomal gene will assort based on the alleles existing and are usually hypothesized to be unlinked gene with a ratio of
