The karyotype of a child born with Down syndrome includes a trisomy in chromosome number 21. The rest of the karyotype remains normal.
<h3>What is a karyotype?</h3>
A karyotype is a representation to indicate the chromosomes of a somatic cell in an individual.
In humans, somatic cells are diploids, thereby karyotypes will be formed by two sets of homo-logous chromosomes.
Down syndrome is caused by the presence of an additional chromosome number 21, and therefore the karyotype will exhibit three (trisomy) 21 chromosomes.
