Cytokinesis is the meiotic event that would mostly cause Williams syndrome.
What is Williams syndrome?
Williams syndrome (Williams-beuren syndrome) is a rare genetic disorder. It is characterized by delays in growth before and after birth, varying degree of mental deficiency, short stature, and distinctive facial features that become pronounced with age.
The syndrome can be usually identified when the child is a baby or during early childhood.
Williams syndrome occurs due to loss/ deletion of genetic material of specific part of chromosome 7. There are 25 to 27 genes in the deleted region, and many believe that the loss of many of these genes is what contributes to the characteristic features of the syndrome.
A person with Williams syndrome is usually overfriendly, highly sociable, empathetic, with some anxiety relating to social events.
Therefore, Cytokinesis is the meiotic event that would mostly cause Williams syndrome.
