Why do population have variations in certain traits?
For one thing, different individuals have different alleles.
When two alleles in a pair are different?
When the alleles are different the organism is heterozygous for that trait. Another way of putting it is to say the genotype is heterozygous for that trait. The dominant allele will be seen in the phenotype ie what is displayed.Most traits are governed by more than one pair of alleles.
What is the difference between alleles and multiple alleles?
Alleles refer to different versions of the same gene. So a single gene can have multiple alleles. For example in fruit flies there is a single gene that controls eye color, and the eye color of the fly depends on the alleles they have for that gene (since they have two copies of every gene, being diploid). A polygenic trait refers to any inheritable trait that is controlled by multiple genes, and each of these genes can have multiple alleles. For example, eye color in humans is a polygenic trait. There are at least three different genes, each with multiple alleles, that determine eye color in humans. Polygenic traits don't follow patterns of mendelian inheritance. So in summation the difference is multiple alleles refers to different versions of one gene and polygenic traits refers to a single trait which is controlled by multiple genes (each with multiple alleles) Yes, or: Multiple alleles are "the existence of more than two alleles (versions of the gene) for a genetic traits. Polygenic traits are "[characteristics of organisms that are] influenced by several genes." So multiple alleles are more than two alleles for one trait, and polygenic traits are one trait that is influenced by multiple genes. This information came from my biology textbook, "Biology: Principles and Explorations" by Holt, Rinehart, and Winston.
What traits are controled by a gene with multiple alleles?
Some of the human traits determined by multiple alleles would be hair color, hair texture, eye color, built, physical structures, etc. One notable and most common example of multiple alleles in humans would be of the blood groups.
Explain segregation of alleles using pea plants?
if the pea plant has 2 recessive alleles then the plant is gonna come out short.but if it has 1 recessive and one dominant allele then the plant turns out tall, because the dominant allele can be present without the recessive allele.

How are recessive and genes related?
If you are talking about traits, dominant traits and recessive traits both have alleles. Dominant traits are alleles that cover up the expression of other alleles. One dominant allele with one recessive allele makes a dominant trait. Two dominant alleles together also make a dominant trate. Recessive traits are alleles that are only expressed when there is no dominant trait to cover them up. Two recessive alleles make a recessive trait. Traits can be passed over to the next generation. Two alleles together make a genotype, which is the inherited combination of alleles. Alleles: different versions of the same gene. Heredity: determined by genes. Genes: piece of DNA that shows the cell how to make a protein it needs.

The law of independent assortment states the the inheritance of alleles for one trait is not affected by the inheritance of alleles for a different trait if the genes for the traits are on?
separate chromosomes
What is the definition of alleles?
An allele is one possible coding sequence that can be in a gene. Often one gene will have several different possible alleles (e.g. for hair color). Alleles are now understood to be alternative DNA sequences at the same physical locus, which may or may not result in different traits.
How do traits get inherited?
Through genetics, you have two alleles(different versions for a gene) for each gene, one from each parent
What does it mean if there is two different alleles for a trait?
The trait could show up in two different forms. Alleles are individual units that determine what trait will be expressed in an offspring. Alleles exist for most traits such as hair color or wing size. Having two alleles simply means that the trait can be expressed in different variation. One trait can have several different alleles.
How are dominant and recessive genes related?
Dominate them. Recessive alleles do not show in your phenotype unless you have two of the same recessive allele. But if you inherit one dominant and one recessive, it is the dominant that always shows in your phenotype.
Two ways multiple alleles and polygenic traits differ?
Multiple alleles are "the existence of more than two alleles (versions of the gene) for a genetic traits. Polygenic traits are "[characteristics of organisms that are] influenced by several genes." So multiple alleles are more than two alleles for one trait, and polygenic traits are one trait that is influenced by multiple genes.

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
