Nondisjunction is defined as the failure of the chromosomes to seperate during cell division. An animal with a haploid number of 6 (diploid number of 12) undergoes meiosis, and at the meiosis II (cells are already haploid from the meiosis I), nondisjunction occurs. The mature ovum will contain 6+1 chromosomes (n+1) because there is an extra chromosome from the nondisjunction. The second polar body will contain 5 chromosomes (normal would be 6) because the second polar body did not receive that extra chromosome due to nondisjunction. In the event of fertilization of the abnormal ovum with a normal sperm, the zygote will be a diploid (12 chromosomes) normally but since the ovum as an extra chromosome from the nondisjunction then the zygote will have an extra chromosome (13 chromosomes). One pair of chromosomes has an extra single chromosome and this is called a trisomy.
Hi there!
From a personal view, I believe it would be best to talk about your problems. By holding everything inside, you're emotions might get the best of you, and you might just explode! Not literally, but you're emotions might all come out at once, and most likely you probably won't know where there coming from. For example, say your mad because your family doesn't pay attention to you, Instead of communicating to them what's wrong, you bottle your emotions up inside, and the next day you get mad over the smallest thing. By talking your problems out, you may get a better ideal on how to handle them, and you won't be as worried as much.
I hope this helps!
