Explanation:
The probability of a singular paternal chromosome been found in a specific gamete = 1/2
Therefore, the probability that all the three would have a paternal source = (1/2)^n
Where,
n = 3
(1/2)^3
= 1/8
Of course-true- without variation evolution would not existd

Answer:
Sister chromatids.
Explanation:
Sister chromatids are the two identical halves of a chromosome that are held together at centromere with help of cohesin. DNA replication in the S phase of the cell cycle doubles the amount of DNA. The copies of the DNA formed during DNA replication are accommodated in sister chromatids. Hence, two sister chromatids of a chromosome carry the identical DNA helices and associated proteins.
