Not even identical twins have the same DNA--although theirs would be far closer than anyone else's. DNA changes over time. Odds of two siblings having the same DNA who did not split from the same zygote are vanishingly small. If the current population of the earth was your sister, it is unlikely another person would have DNA close enough to yours they could be mistaken for your identical twin.
The odds of two unrelated people sharing the same DNA is substantially smaller yet.
What else can I help you with?
How is it possible that 2 people with the same genome could be different?
Variations in gene expression, environmental factors, and lifestyles can all contribute to differences in individuals with the same genome. Epigenetic modifications, such as DNA methylation and histone modification, can also play a role in gene expression. Additionally, random mutations can accumulate over time, leading to genetic diversity between individuals with the same genome.
What helps to solve crimes because no two people have the same DNA except identical twins?
DNA analysis is a powerful tool in solving crimes because each person's DNA is unique, except for identical twins who share the same DNA. By comparing DNA evidence found at a crime scene to that of a suspect or a database, forensic analysts can link individuals to the scene and provide important evidence in legal proceedings.
Are a DNA fingerprint and a genetic fingerprint the same?
no its classed as a making of your body for people such as police or crime scene investigators
What are the possible DNA combinations that can result from genetic recombination during meiosis?
During genetic recombination in meiosis, the possible DNA combinations that can result are a mix of genetic material from the two parent cells, leading to new combinations of alleles and variations in the offspring's DNA.
Does DNA replication take place in the same direction along both strands of the DNA?
No, DNA replication does not take place in the same direction along both strands of the DNA. It occurs in opposite directions on the two strands, known as the leading and lagging strands.
Is it possible that two people could have the same dna?
It is possible for identical twins to have identical DNA, but very often that is not the case.
Is it possible to test for maternity between two sisters or can their DNA be the same?
I think this is related... No two people on earth can have the same DNA (genetics) so they wont be the same although they will be simalar though it is possiable to distinguish brother from sister, mother from daughter etc.
The process of DNA fingerprinting is based on what fact?
that no two people have the exact same DNA
Can two people have the same hallucinations?
It is possible.
What are two called if they have the same DNA?
Two such people would be 'identical twins' . In every other case DNA is unique to each person.
Is it possible to fancy two people at the same time?
It is very possible to fancy two people at the same time, sometimes you just have to realize who you can picture yourself with.
Is it possible for two people to have the exact same RFLP banding pattern?
It is highly unlikely for two people to have the exact same RFLP banding pattern due to the vast genetic variability among individuals. RFLP analysis is based on variations in DNA sequences, making it improbable for two unrelated individuals to have identical patterns.
Is it legally possible to be married to two people at the same time?
No, it is not legally possible to be married to two people at the same time in most countries as it is considered bigamy, which is illegal.
How is it possible to love two people at the same time?
It is possible to love many people at the same time, and most people do. We have an infinite capacity for love.
Can two people have the same pain at the same time?
Its possible, and can be explained by coincidental inference.
Is it possible that two different people with two different DNA strands can have the same oral bacteria?
Yes, it is possible for two people with different DNA strands to have the same oral bacteria. The composition of oral bacteria is influenced by factors such as oral hygiene practices, diet, and environmental exposure, rather than solely genetics. Thus, individuals with different DNA can share similar oral bacterial profiles.
Why does using more regions of the genome decrease the probability that two people would have the same DNA fingerprinting?
Using more regions of the genome increases the complexity of the DNA fingerprint, making it less likely for two people to have the same combination of alleles at all the regions. This decreases the probability of finding two identical DNA fingerprints in a population.
