Summary
Genetic markers on both the autochromosome and X-chromosome can confirm full sibling sisters. This study explored methods for identifying sibling relationships using these genetic markers.
Area of Science:
- Forensic Genetics
- Human Genetics
- Molecular Biology
Context:
- Establishing full sibling relationships is crucial in various legal and familial contexts.
- Traditional methods often rely on autosomal markers, but X-chromosome markers offer complementary information.
Purpose:
- To explore and validate methods for identifying full sibling sisters using genetic markers.
- To assess the utility of both autosomal and X-chromosomal genetic markers in sibling identification.
Summary:
- Genomic DNA from sibling sisters was analyzed using 15 autosomal Short Tandem Repeats (STRs) and 17 X-chromosomal STRs.
- Additionally, 11 X-chromosomal Single Nucleotide Polymorphisms (SNPs) were genotyped.
- Full sibling relationships were confirmed using autosomal STRs and supported by shared alleles on the X-chromosome.
Impact:
- Demonstrates that X-chromosome genetic markers, in addition to autosomal markers, are valuable for confirming full sibling relationships.
- Enhances the accuracy and reliability of forensic genetic analysis in sibling identification cases.

Comparing Copy Number Variations and SNPs
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Single Nucleotide Polymorphisms-SNPs
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
Genome-wide Association Studies-GWAS
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

Attachment of Sister Chromatids
As cells progress into mitosis, the nuclear envelope breaks down, and the condensed chromosomes are exposed to the array of bipolar microtubules of the mitotic spindle. The kinetochore, a large, disc-shaped protein complex, is present at the centromere region of the sister chromatids and acts as a binding site for the microtubules. Usually, the plus-end of a single microtubule is embedded within the kinetochore. However, some kinetochores first establish lateral contact with the side-wall of a...

Separation of Sister Chromatids
At the transition from prophase to metaphase, there is a reduction in cohesion along the chromosomal arms, resulting in the resolution of sister chromatids. However, residual cohesin connections remain to hold the sister chromatids together until the transition from metaphase to anaphase. The residual connection prevents any premature separation of sister chromatids, blocking the risks of aneuploidy within the daughter cells.
