Question

Quizplus · Accepted Answer

Monosomy is the condition in which there is only a single copy of an autosome in a diploid cell. This can occur due to a nondisjunction event during meiosis, resulting in the loss of one chromosome. Trisomy, on the other hand, is the presence of three copies of an autosome in a diploid cell, and is commonly seen in conditions such as Down syndrome. Diploidy refers to the normal state of having two copies of each autosome in a diploid cell. Polyploidy refers to having more than two sets of chromosomes, while haploidy refers to having only one set of chromosomes.
