what is d difference between (a) reproduction and foetus
(b) twins and clones
Reproduction | Foetus |
Reproduction is a characteristic feature of all living organisms. It involves the creation of organelles, cells, or organisms of the same kind. Reproduction is necessary for the survival of a particular species. During reproduction, the information for inheritance of characteristics is passed on from the parents to the offsprings in the form of DNA. | Foetus is a young human being, animal, bird etc in the early stages of development before it is born or hatched. |
True Twins (identical twins) | Clones |
A true twin is the result of the splitting of one egg in two identical ones. | Clones derive from a foreign egg implanted with the DNA of the donor. |
True twins often look almost exactly the same and share the same DNA | Clones may exhibit a slight genetic difference from its donor. |
True Twins are born at the same time as one another. | Clones are created later and commonly known as ‘delayed twin’. |
True Twins are a natural occurrence. | Clones are the genetically engineered organisms. |
True twins are inexpensive and easy process | Cloning is a very difficult, expensive, painstaking process. |
No ethical issue arises and it is considered legal. | People are concerned about the ethics of such a development of clone. |
True twins share a womb with the original animal. | Clones do not share a womb with the original animal |
Success rate of true twins is higher than clones. | Success rate of clones are lower than true twins. |
