Fusion of a normal gamete (n) with a gamete missing a chromosome (n − 1) gives rise to a zygote with a condition called ____.

A) ​trisomy
B) ​monosomy
C) ​polyploidy
D) ​monoploidy
E) ​translocation

The fusion of a normal gamete with a gamete missing a chromosome results in a zygote with only one copy of that chromosome, a condition known as monosomy. Trisomy would occur if the zygote had an extra chromosome, polyploidy refers to having multiple sets of chromosomes, and monoploidy refers to having only one set of chromosomes rather than the normal two sets. Translocation refers to the movement of genetic material from one chromosome to another.
