In the process of gametogenesis, nondisjunction during meiosis II results in at least one pair of sister chromatids failing to separate. Consequently, this leads to the formation of two cells containing the typical haploid chromosome count (n), one cell with an additional chromosome (n + 1), and a fourth cell missing a chromosome (n - 1). To summarize, the outcome is two gametes with n, one with n + 1, and one with n - 1.

Answer:
Explanation:
Various materials will respond to heat differently, altering their temperature at distinct rates, due to the differing heat absorption capacities of these materials.
The independent variable in an experiment is the one that is deliberately modified or adjusted in order to observe its effects.
In this case, the varying amounts of caffeine administered to the dogs are the factor that changes—the control group receives no caffeine, the second group gets 10 mg of caffeine, while the third group gets 50 mg of caffeine each.
Thus, the amount of caffeine given to the dogs is the independent variable being altered.
