Answer:
d. Meiosis II in the father
Explanation:
Since the son has two extra Y chromosomes, the nondisjunction would have occurred in father because females do not have Y chromosome. Before Meiosis DNA replication occurs during which the homologous chromosomes are replicated. During Meiosis I crossing over occurs and homologous chromosomes separate from each other. During Meiosis II sister chromatids of a chromosome separate and move into individual daughter cells.
Here, during Meiosis II the sister chromatids of Y chromosome did not separate from each other (nondisjunction). They collectively moved to one daughter cell. As a result one daughter cell had two Y chromosomes and other daughter cell had none. When the daughter cell containing two Y chromosomes combined with the daughter cell containing one X chromosome from mother, XYY individual was born.
<span>Mitosis is a process of cell replication because in this process a parent cell will double its content (DNA,organelles, cytoplasm) and then separate them in to two identical cells. The replication is </span><span>the ability of a cell making two exact replicas of its DNA.
Another example of cell replication is meiosis.

Run more trials for the experiment to ensure that the small difference is not significant. B
Answer:
I personally think that all the methods could potentailly work but I would have to go with "A" as usaully GPS's are used as they are more simple and easier to have in a collar, as radio technology is probably the number one most used by people such as scientists
