alleles are different variations of the same gene. For instance, one allele may give blue eyes, but another may give brown eyes, but both are the eye colour gene.
(This is a simplification, eye colour is controlled by more than one gene but for the sake of this example let's pretend it's just one)

∙ 12y agoAlleles are in genes.
Think of it this way :
Using the eye colours BROWN and GREEN. Brown eyes are more common than green eyes so brown would be the dominant allele and green would be the recessive allele.
We'll use the letter E. Brown, because it's dominant will be capital and green because its recessive will be the lower case e.
Ee = this would equal brown eyes in a child because dominant beats recessive
EE = would also equal brown eyes because there is no green eye ALLELE
eE = Brown eyes you will get again
Now if it's ......... ee = that will equal green eyes because there is no dominant brown eye allele.
That's why brown eyes are more common than green, hope this helped.

How are multiple alleles different from polygenic traits?
Multiple alleles are genes that have more than two alleles. An example of this would be blood types, with ABO as three separate alleles.Polygenic traits are traits whose phenotype rely on alleles from different genes. An example of this would be hair type, which relies on genes from different parts of chromosomes.The main difference is that multiple alleles are genes with 3 or more alleles; polygenic traits do not necessarily have more alleles, but they rely on on multiple genes.
What is the difference between homozygote-and-heterozygote?
The difference between the two is that a homozygote is an organism that has two identical genes at the same place on two corresponding chromosomes and a heterozygote desribes a cell or orangism that has two or more different versions of alleles of at least one of its genes
What are the multiple forms of genes called?
Alleles are genes that exist in multiple forms.
What are contrasting forms of genes called?
Alleles
What is the difference between chromosomes and genes?
DNA is in genes, and genes are in chromosomes.

What are the multiple forms of genes called?

How alleles and genes related?
Genes and alleles are related because alleles are inside a gene. Genes are made up by alleles. A gene is DNA. The allele is like piece of DNA inside a gene.
What is the connection between genes and alleles?
they both show something about appearance.
What are the alleles of a gene?
That depends on the gene: some genes have only a few alleles, some genes have hundreds or even thousands of alleles.
What are contrasting forms of genes called?
Alleles
What three ways are human traits controlled?
Single genes with two alleles, single genes with multiple alleles, and many genes that act together
What is the difference between chromosomes and genes?
DNA is in genes, and genes are in chromosomes.
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 is difference between segregation and independent assortment?
Every diploid cell has two alleles for every gene. Segregation means that when these alleles go through meiosis to create gametes, they will segregate from one another, and each of the haploid gametes will end up with only one allele.Independent assortment comes into play when you are looking at how the alleles of two genes separate. As long as each gene lies on a different chromosome, then the alleles of these genes will assort themselves independently of one another when the haploid gametes are formed in meiosis. Each haploid gamete can end up with a different combination of alleles of these two genes.
