Postnatal development of parthenogenetic—fertilized mouse aggregation chimeras
Chimeras were made from parthenogenetic and fertilized cleavage-stage mouse embryos. The perinatal mortality was high. The parthenogenetic contributions to different tissues at birth ranged from 0 to 50%. No selection of parthenogenetic cells was observed in the pigmentation of the coat, but this does not exclude that such selection could act in other tissues. The weight of chimeras at birth ne...
متن کاملEmpirical Studies of Clone Mutation and Clone Migration in Clone Genealogies
Duplications and changes made on code segments by developers form code clones. Cloned code segments are exactly the same or have a particular similarity. A set of cloned code segments that have the same similarity with each other become a clone group. A clone genealogy contains several clone groups in different revisions and time periods. Based on different textual similarities, there are three...
متن کاملTo clone or not to clone?
To clone... Or not to clone? That is a good question! Cloning has its advantages, but also its disadvantages. We might not realize what we are doing. It is like a sword with two blades. On one hand, it can save many lives. On the other hand, it can do a lot of harm. A question mark hangs over the future of cloning. Who are we to decide about someone’s life, his future, his happiness?
متن کاملClone Removal V/S Clone Avoidance
Cloning occurs in software when there is redundancy in it in form of any similarity. So, the clones need to be removed or it can be avoided from the software in order to mitigate the negative impacts of clones. In this paper we have studied the various factors that affect the decision of avoidance or removal of clones for handling them.
متن کاملTo Enhance Type 4 Clone Detection in Clone Testing
The means of software reuse is copying and modifying block of code that detect cloning. As a survey, it is observed that 20-30% of module in system may be cloned. So it is mandatory to detect clones in system to reduce replication and improve reusability. Code clone is similar or duplicate code in source code that is created either by replication or some modifications. Clone is a persistent for...
