#### Question

Suppose that meiosis occurs in the transient diploid stage of the cycle of a haploid organism of chromosome number n. What is the probability that an individual haploid cell resulting from the meiotic division will have a complete parental set of centromeres (that is, a set all from one parent or all from the other parent)?

Verified

#### Step 1

1 of 2

Since the parental set of centromeres can be from the male or female parent, the probability of an individual haploid cell to obtain a set from one parent is $\dfrac {1}{2}$. If there are $n$ chromosomes, the probability of a parent with all the centromeres is ($\dfrac {1}{2}$)$n$. Hence, the complete set of centromeres from a parent can be computed by 2($\dfrac {1}{2}$)$n$.
