What are the possible outcomes of the following cross
2 answers:
Answer:
The letter B is the right answer.
Explanation:
The diagram above shows an example of a punnet square. The punnet square is the easiest way to observe the result of a cross.
To solve the punett square, you must first know the genes of the parents, which in this case are "Tt" and "Tt". You will separate each pair of these genes and place each letter of the first pair in a space on the first line of the punnet square. You will do the same with the second pair of genes and place each letter to occupy a space in the first row of the punnet square. After that, just add the letters, that is, T + T = TT, T + t = Tt, T + t = Tt and t + t = tt.

A and B are wrong, because chemical reactions involve electrons.
D is wrong, because the splitting of a nucleus is fission.
