| Modern Genetic Analysis Chapter 8. Chromosome Mutations Changes in Chromosome Number Figure 8-2. Two possibilities for the pairing of three homologous chromosomes before the first meiotic division in a triploid. Notice that the outcome will be the same in both cases: one resulting cell will receive two chromosomes and the other will receive just one. The probability that the latter cell can become a functional haploid gamete is very small, however, because to do so it would also have to receive only one of the three homologous chromosomes of every other set in the organism. Note that each chromosome is really a pair of chromatids.
