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.

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
Natural selection causes the frequency of favorable alleles to?
Increase.
What is prerequisite for evolution?
That organisms vary, by sexual recombination or mutation. That some organisms will be better at survival and reproduction so that their alleles are passed on to progeny and these causes a change in frequency of these alleles over time which is the definition of evolution.
How do you think crossing over affects the number of different types of gametes that are formed?
You get four choices of gene, of which two are randomly selected. Although sometimes these genes are the same, often they are not all identical. this results in different genotypes and therefore phenotypes being experienced.
How do natural selection cloning and selective breeding lead to evolutionary change?
The only thing that causes evolution is Mutations due to forced natural selection of desired alleles.

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.

What causes the difference between breccias and conglomerante?
The difference between breccias and conglomerate is that breccias are angular and conglomerates are smooth. What causes rocks to be smooth is transportation, such as when rocks are in a stream and are worn down. Therefore transportation is what causes the difference between breccias and conglomerates.
Difference in a charge between two electrodes in a cell causes a ----between electrodes?
Potential difference.
What causes the difference in colors emitted by different colors?
different wavelengths from different colours
What is the difference between a tree and a stack?
what is the causes of asthma
Natural selection causes the frequency of favorable alleles to?
Increase.
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.
What difference between consequence and causes?
Causes is actually "how" whereas consequences is "what happened" or the results or effects
