Each P1 parent of a monohybrid cross has completely identical genes<br> ture<br> false
lawyer [7]

Answer:

False.

Explanation:

Monohybrid cross may be defined as the cross done by taking the single character at the time. The monohybrid cross explains the concept of dominance and law of segregation.

The P1 parent of monohybrid cross doesnot have completely identical genes. This can be explained by the cross shown below:

Parent         Tt           ×       tt

Gamete         T  t           ×     t

Here, the parents are not identical.  

Thus, the answer is falsi.

Do organisms intentionally mutate
kirza4 [7]

Well, the problem is that a mutation is actually either a deletion or insertion within a sequence of nucleotides, things that make up a gene. Now, in later generations of offspring, genes will mutate randomly on their own anyway.
