A persons specific DNA type, the strands that separate them from others and determine their characteristics and traits such as hair color, eye color, height. The STR alleles are different in every person because no two people are alike and no two people have the same repeated patterns within their 13 strands of DNA.
The difference between different short tandem repeat (STR) alleles is caused by variations in the number of repeats of a specific sequence in the DNA. Mutations, such as insertions or deletions of repeating units, contribute to the diversity of STR alleles found in individuals. These variations in the number of repeats at a particular locus create unique genetic profiles that can be used for identification purposes in forensic and paternity testing.

A husband and wife have two sons one boy has a straight thumb while the other has a bent thumb what causes the difference?
The brothers have different alleles. They received different alleles from their parents
How do you think crossing over affects the number of different types of gametes that are formed?
Crossing over increases genetic variation by shuffling alleles between homologous chromosomes. This can generate a wide variety of different gametes through the combination of different allele arrangements. As a result, crossing over increases the number of different types of gametes that can be formed during meiosis.
Natural selection causes the frequency of favorable alleles to?
increase in a population over time, as individuals with those alleles are more likely to survive and pass them on to their offspring. This process leads to the evolution of populations that are better adapted to their environment.
How does crossing over and nondisjunction contribute to variation and increase genetic diversity in a population?
Crossing over during meiosis results in the exchange of genetic material between homologous chromosomes, leading to new combinations of alleles in offspring. This increases genetic diversity by shuffling alleles within a population. Nondisjunction can result in an incorrect distribution of chromosomes during meiosis, leading to aneuploidy and new genetic variations, which can also contribute to genetic diversity in a population.
What factors change the allele frequency of a population?
Factors that can change the allele frequency of a population include natural selection, genetic drift, gene flow, mutations, and non-random mating. Natural selection favors certain alleles, genetic drift causes random changes, gene flow introduces new alleles, mutations create new variation, and non-random mating can lead to specific alleles being passed on more frequently.

What is the difference between an allele and a gene?
A gene is a part of the DNA. Alleles on the other hand refer to different versions of the same gene. There are other more subtle differences between the two and this is what we are going to explore on this page:Genes are the different parts of the DNA that decide the genetic traits a person is going to have. Alleles are the different sequences on the DNA-they determine a single characteristic in an individual.Another important difference between the two is that alleles occur in pairs. They are also differentiated into recessive and dominant categories. Genes do not have any such differentiation.An interesting difference between alleles and genes is that alleles produce opposite phenotypes that are contrasting by nature. When the two partners of a gene are homogeneous in nature, they are called homozygous. However, if the pair consists of different alleles, they are called heterozygous. In heterozygous alleles, the dominant allele gains an expression.The dominance of a gene is determined by whether the AA and Aa are alike phenotypically. It is easier to find dominants because they express themselves better when they are paired with either allele.Alleles are basically different types of the same gene. Let's explain this to you in this way- If your eye color was decided by a single gene, the color blue would be carried by one allele and the color green by another. Fascinating, isn't it?All of us inherit a pair of genes from each of our parents. These genes are exactly the same for each other. So what causes the differences between individuals? It is the result of the alleles.The difference between the two becomes more pronounced in the case of traits. A trait refers to what you see, so it is the physical expression of the genes themselves. Alleles determine the different versions of the genes that we see. A gene is like a machine that has been put together. However, how it will works will depend on the alleles.Both alleles and genes play an all important role in the development of living forms. The difference is most colorfully manifest in humans of course! So next time you see the variety of hair color and eye color around you, take a moment and admire the phenomenal power of both the gene and the allele!Summary:1. Genes are something we inherit from our parents- alleles determine how they are expressed in an individual.2. Alleles occur in pairs but there is no such pairing for genes.3. A pair of alleles produces opposing phenotypes. No such generalization can be assigned to genes.4. Alleles determine the traits we inherit.5. The genes we inherit are the same for all humans. However, how these manifest themselves is actually determined by alleles!
What causes a wide range of phenotypes for some traits?
Some traits, such as eye color and hair color, have multiple alleles that control different aspects of the phenotype. Because there are multiple different possible combinations of alleles, you get a wide range of phenotypes.

Do humans have alleles?
It's the other way around: natural selection is the natural process that causes the frequencies of occurence of alleles in the population gene pool to shift.
What causes the difference in colors emitted by different colors?
different wavelengths from different colours

What causes varation in traits?
Genotypic variation is caused by mutation. Phenotypic variation can be caused by mutation, which gives rise to different alleles, or it can be caused by environmental factors.
Why the water levels in the various Manometer tubes are different?
The water levels in different manometer tubes are different because they reflect the pressure differences between two points in a system. The height difference in the tubes indicates the pressure differential between the two points they are measuring. This pressure difference causes the fluid to rise or fall in each tube to balance the pressures.
