The offspring could have three X chromosomes or two X chromosomes and a Y chromosome.
The term ploidy indicates the number of complete sets of chromosomes in a cell. This can be haploid (one set of chromosomes), diploid (two sets), triploid (three sets), and so on. For example, humans are typically diploid, with two sets of 23 chromosomes each.
Diploid is the term for cells that contain two chromosomes of each pair. Euploid is a term meaning normal body cells.
HeLa cells are known to have a triploid karyotype, which means they have three sets of chromosomes instead of the usual two sets found in diploid cells. This results in HeLa cells having around 69-82 chromosomes.
People with Down syndrome, also called mongoloidism have 47 chromosomes. Having 65 chromosomes would be lethal, as normally having 47 chromosomes is lethal. Down syndrome is also known as trisomy 21, because instead of two copies of chromosome 21, a person with Down syndrome has three copies, which accounts for the 47th chromosome.
The offspring could have three X chromosomes or two X chromosomes and a Y chromosome.
Down's sydrome is caused by trisomy 21, when there are three 21st chromosomes instead of the normal two.
It is certainly possible to have more than 46 as in Trisomy 21 (or down syndrom) where "one cell has two 21st chromosomes instead of one, so the resulting fertilized egg has three 21st chromosomes".

An organism with the chromosome designation 3n is called triploid. Triploid organisms have three sets of chromosomes instead of the usual two sets found in diploid organisms. This can lead to infertility and developmental abnormalities in some species.
The term that describes the condition in which a cell contains two sets of homologous chromosomes is "diploid." In humans, diploid cells have a total of 46 chromosomes, with 23 pairs of homologous chromosomes.
An organism that contains more than two sets of chromosomes.
Fruit flies have three pairs of chromosomes, two autosomes and one pair of sex chromosomes (XX in females and XY in males).
People with Down syndrome, also called mongoloidism have 47 chromosomes. Having 65 chromosomes would be lethal, as normally having 47 chromosomes is lethal. Down syndrome is also known as trisomy 21, because instead of two copies of chromosome 21, a person with Down syndrome has three copies, which accounts for the 47th chromosome.
