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.

Two strands of DNA double helix are said to be anti-parallel which means that while one of the strands runs in the 5'→3' direction, the other one runs in the opposite direction, i.e. 3'→5' direction.

The anti-parallel nature of the two strands in a DNA double helix simply means that if one strand has the polarity 5'→3' then the other exhibits opposite polarity, i.e. 3'→5'. The DNA double helix model was put forward by Watson and Crick in the year 1953 which was based on the X-ray diffraction data generated by Maurice Wilkins and Rosalind Franklin. The DNA molecule is made up of two strands that are joined together with the help of Hydrogen bonds.

The total number of genes passed from parents to kids is known as a genotype. An alternative definition of a genotype is the entire collection of heritable genes that can be passed from one parent to the next. These genes aid in encoding particular traits and qualities that an organism can physically express (phenotype).

The three genotypes are homozygous dominant (PP), Heterozygous (Pp) and Homozygous (pp).

The observable qualities or characteristics of an organism that are the outcome of the interplay between genes and environmental variables are referred to as phenotypes. These characteristics include outward appearances and any other characteristics we can see.

An organism's physiology, biochemistry, and behaviour are all part of its phenotype. The phenotype is influenced by lifestyle choices and environmental variables, in contrast to genotype, which is inherited from the parents.

The bicoid starts a regulatory gene cascade that leads to segment differentiation along the fly embryo’s anterior-posterior axis.Hox, segmentation, and effector genes are among these genes.

There are numerous genes that encode transcription factors, and these transcription factors in turn cause the production of more transcription factors, causing cascades of gene expression that amplify the initial signal via various signalling pathways.In fruit flies, approximately 25 genes control the differentiation of the embryo into discrete segments, resulting in changes in the number and organisation of the segments. Mutations in these genes frequently result in the disruption of entire groups of segments.Hox genes, a family of homeotic transcription factors, play a crucial role in controlling the body design along the craniocaudal axis.The Bicoid and Nanos gene products can be used to identify the anterior-posterior axis in Drosophila. Nurse cells are responsible for transcription of the bicoid gene’s mRNA. The unfertilized egg contains the bicoid mRNA close to its anterior pole.
