What would happen if the members of one homologous pair did not segregate to opposite poles, but instead both went to the same pole

Daughter cells with abnormal number of chromosomes will be produced (aneuploidy)

Explanation:

Ideally, homologous pair of chromosomes are meant to separate into opposite poles during the anaphase I stage of meiosis. However, a failure to separate, a process called MEIOTIC NON-DISJUNCTION, will cause some daughter cells to have more than the required/normal chromosome number while some daughter cells will have less than the normal or no chromosome.

This abnormality in chromosome number caused by failure of chromosome to separate is called ANEUPLOIDY. In a nutshell, when this occurs, the daughter cells will possess abnormalities in chromosome number i.e trisomy, monosomy etc.

it will increase due to the time span
