Answer:
It will cause an Aneuplidy , an abnormal number of chromosomes that cause a fail on the chromosomes to separate at meiosis.
Explanation:
Abnormalities in chromosome number are the most obvious chromosomal disorder and are referred to as aneuploidy. It`s a condition in which one or more chromosomes are present in extra copies or are deficient in number, but not a complete set.
The loss of a single chromosome from a diploid genome is called monosomy and the gain of one chromosome is called trisomy, caused by nondisjunction, which occurs when pairs of homologous chromosomes or sister chromatids fail to separate during meiosis.
Misaligned or incomplete synapsis, can cause nondisjunction.
The risk of nondisjunction increases with the age of the parents.
I hope it helps!
