The answer is Meiosis in egg Formation.
Non disjunction is caused by the failure of paired chromosomes to separate during cell division. In meiosis it can occur in meiosis I and meiosis II, if it occurs in meiosis I, it means that at least one pair of homologous chromosomes did not separate. The end result is two cells that have an extra copy of one chromosome and two cells that are missing that chromosome.
I choose to list two. The two that form the basis are evergreens and broadleaf trees.
Answer:
The tetrad occurs during the first phase of meiosis. It is the foursome of chromatids that forms when replicated homologous chromosomes align. It must be formed for crossing over to occur. It is broken apart when the homologous chromosomes separate in meiosis I.

Since ALD is an x-linked recessive disease, women must have 2 affected x chromosomes in order to get the disease, which is unlikely because the disease is rare. Since men only have one x chromosome, they will have the disease if they inherit an affected x chromosome.
