As a human, you have 23 pairs of chromosome. For each pair, one chromosome was maternally derived and the other was paternally derived. During meiosis, chromosome pairs are segregated randomly into haploid cells so that the maternal and paternal chromosome pairs are split up.
a. What is the probability that a human gamete has 20 of 23 maternally derived chromosomes?
b. Which Mendelian principle is responsible for the number of maternally-derived and paternally-derived chromosomes that end up in gametes?
c. What is the probability of having at least one maternally derived chromosome in a gamete?
