A Down syndrome Karyotype: The present genetic condition is an abnormality of chromosome 21, instead of a pair, an extra chromosome 21 present in a genome. Therefore, not 46, but 47 chromosomes are present in a baby with a present genetic condition. How it happens that we will discuss in the upcoming section. But first see the image of trisomy 21.
