A Punnett square can't show the actual results of a cross (D.) because the actual results happen according to which gametes happen to meet.
So a Punnett square might say that two people could have two daughters with normal vision: one son with normal vision: one son who is colorblind. That's just the probability. Obviously, those won't be the results if they just have one child!
A. is shown in the square.
B. The square does show genotypes of the offspring. Even if they only have one offspring, that offspring's genotype is in the Punnett square.
C. The square has the alleles from one parent on the side and the alleles from the other parent on the top.

The Punnett square is a diagram designed by Reginald Punnett and used by biologists to determine the probability of an offspring having a particular genotype. It is made by comparing all the possible combinations of alleles from the mother with those from the father.
With this information hope that you can find the answer by yourself

this is feasible. even nevertheless, a number of the somewhat common varieties of existence began while the atmosphere of the worldwide became lots diverse from what this is now or what could probable be in destiny and that i do no longer think of this is feasible to 3 how recreate that atmosphere. case in point. existence began while the earth became nonetheless youthful and its temperature became lots bigger than what this is as we communicate; or maybe nevertheless worldwide warming is occurring i do no longer think of this is going to ever be feasible to extend the temperature to the tiers of the early days of Earth. the different subject that became lots diverse thousands of years in the past is the composition of the ambience. besides the reality that Evolution tells us that each and each physique the species have a common ancestor, it would not recommend that in the time of the destiny guy can evolve from mouse. actually diverse species differentiated from that common ancestor many some years in the past. and that i do no longer think of that this is feasible to recreate each and each physique of those species with out having that common ancestor. And bearing directly to the rat inhabitants, this is going to ultimately bypass down as quickly as they devour all the fit for human intake textile on earth.

it won't show the actual results, just the 4 results that is could be
