Question: fathers contribute more new point mutations to their children than...

Question details

Fathers contribute more new point mutations to their children than do mothers.

Which one of the human chromosomes will have accumulated the greatest frequency of point mutations as it passes through many generations of human evolution?

a.

The X chromosome will accumulate the most point mutations over human generations,

because males carry only one copy of this chromosome and that leaves it more exposed and less hidden to mutagenic factors.

b.

The Y chromosome will accumulate the most point mutations as it passes through generations of humans,

because a copy of the Y chromosome is in males for every generation while all of the other chromosomes are in females for some generations.

c.

Chromosome 21 will accumulate the most point mutations over human generations,

because it is the smallest human autosome and an individual can survive even chromosome 21 is present in three copies.

d.

Chromosome 13 will accumulate the most point mutations as it goes through human generations,

because it is the unluckiest of the human chromosomes. (Chromosome 3 will have the fewest, because 3 is a magic number.)

e.

Chromosome 1 will accumulate the most point mutations as it goes through generations of humans,

because it is the largest human chromosome.
