The presented diagram (the presented diagram itself indicates the flow chart) depicts the process of cloning a sheep embryo through a flow chart. The Process is quite complicated (You are not supposed to mix your view and opinion, this diagram never mentions that the process is complicated or simple) as is observed from the diagram (this means the presented diagram- already mentioned in the first sentence “avoid repetition“). A lot of methodology is are involved in this process (over repetition, you can change the word formation instead) for this procedure.
Better If: The presented diagram depicts how cells of sheep pass through different methods and bodies for the purpose of cloning.
It can be clearly seen that the process of reaching from sheep to embryo is five steps long. However Also, (“However” is used to show opposite co-relation, and “also” is used for similarity, you have used both in the same sentence which is a grammatical blunder), an (missing) additional step of impregnating a sheep is also involved in order to deliver the cloned sheep.
Better If: A glance at the chart reveals that the whole process (referencing the cloning) needs three different sheep labeled A, B, and C. Where cells of sheep A and B go through four methods before the embryo’s development, Sheep C is only used as a foster parent.
As can be seen (needs a comma), two female sheep i.e (not recommended to use abbreviation) namely A & and (no symbol in IELTS) B are selected. Then, (missing punctuation comma) the body cell is taken from sheep A through which(whose) DNA is extracted in the(missing article) second step. Similarly, from sheep B egg shell is collected where (whose) nucleus is removed in the(missing article) third step. Furthermore, DNA from sheep A is fused with egg cells (without a nucleus) (check the diagram carefully, it shows that the DNA (blue color) from a body cell is fused with the nucleus(smoky white color) of an egg cell) from sheep B to form a zygote. Then, this zygote undergoes cellular multiplication to form an embryo.
Better If: As is presented, two female sheep namely A and B contribute differently, in particular, a body cell from sheep A and an egg cell from sheep B is used (explaining the trend first). Following this, the DNA extracted from the body cell of Sheep A is fused with the nucleus of the reproductive cell of Sheep B. The so-formed (referencing the whole process) cell is then allowed to divide and redivide till a multicellular structure is formed which is termed an embryo.
Finally (this is not the final step but the second last), the resultant embryo then is placed in the uterus of a(missing article) foster mother(sheep). After the gestation period is over (Nothing mentioned about such period), sheep C gives birth to a(missing article) lamb which is a clone of sheep A due to its DNA (avoid giving your personal opinion).
Better If: For the next step, a new sheep is chosen, Sheep C. The previously formed embryo is now implanted into the uterus of this(referencing sheep c) female sheep which finally gives birth to a lamb, a clone of Sheep A.
