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.
Answer:
Test Variable (independent variable)
Explanation:
X is always the independent variable/time. Test grades is dependent because it's the outcome. Trust me I took the test.
Answer:
Determining Chemical Properties using the Periodic Table. Chemical properties of each element are determined by the element's electronic configuration, and particularly by its outermost valence electrons.
Answer:
c is the correct steps for process of genetic engineering.
The correct answer is option A, that is, the bottle with zero percent concentration.
The control in the given case would have the liquid in it in the absence of any supplemented dissolved solute. So, as to find whether the solution is making the crystal formation or the liquid can do it by itself.
The control refers to one element, which is not changed at all through the experiment, as its unchanging condition permits the association between the other variables being examined to be better comprehended.
