Answer: The ultimate goal of the peer review process is that you can have others review and look over your work for things that are incorrect, need fixing, or need rewording. When we write things on our own, we sometimes make unconscious errors that we sometimes do not even catch in revision. Having a new set of eyes look at something helps to catch errors that we might miss. It is very similar to reading your work out load to catch errors, as reading something out loud is another effective strategy when reviewing your work.

Answer:
Testcrosses clarify linkage because each phenotypic class of progeny corresponds to each gamete type produced by the dihybrid parent.
Explanation:
- A test cross involves the crossing of an individual with another phenotypically recessive individual so as to determine the zygosity of the former by analyses of the proportions of offspring phenotypes.
- In order to determine linkage, the test cross shows that if the parentals are more than the recombinants, we can say that the two genes such as b and c are genetically linked and therefore, they must be on the same chromosome.
- Also, the test-crosses help to find out which alleles came from which parent.
- By setting up testcrosses in which one parent is homozygous for the recessive alleles of both genes,we can analyze the gene combinations received in the gametes from the other, doubly heterozygous parent.
