Alleles affect traits like eye color. Alleles for brown and blue eyes are dominant and recessive respectively. Individuals who have homozygous and heterozygous genotypes with the dominant allele will have brown eyes. However individuals are homozygous for the recessive allele will have blue eyes.

What are inherited traits of fruit flies?
eye color (red/white) and body color (brown/yellow). In fruit flies, eye color is a sex-linked trait determined by a single gene with two alleles. Red color is dominant to white eye color. Body color is an autosomal trait determined by a single gene with two alleles, where brown is dominant to yellow. -Angela B.
How many alleles does a zygote have for each trait?
No - some traits are polygenetic (such as for skin color, eye color, hair color, etc.) and will have multiple alleles.
Skin color in humans caused by several genes at several loci is an example of what multiple alleles at one locus incomplete dominance epostasis or polygenic inheritance?
polygenic inheritance
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.
A single gene has 3 or more alternative forms These are called?
The different forms or variations of a gene are called alleles. Thank you<3
Does a single pair of alleles always determine an individual trait?
No, often many other alleles will also determine the same trait. For example, many alleles put together will determine a person's skin color.

What role do alleles play in the determination of characteristics?
Alleles can be considered as alternative (or "rival") forms of the same general trait. For instance, if we consider eye-color as the product of a single gene (which it isn't), then there exist "blue", "brown", "green" and "grey" alleles for that gene. The eye-color a person ultimately gets is determined by what alleles are inherited by that person from its parents, and how those alleles interact (eg. whether either or both alleles are dominant or recessive, etc).
How many alleles does a zygote have for each trait?
No - some traits are polygenetic (such as for skin color, eye color, hair color, etc.) and will have multiple alleles.
What type of alleles are there?
Some types of alleles are: blood type, hair color, hair type, eye color, etc.
Skin color in humans caused by several genes at several loci is an example of what multiple alleles at one locus incomplete dominance epostasis or polygenic inheritance?
polygenic inheritance
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 chromosome is color vision located on?
Alleles on the X chromosome as well as chromosome 7 can affect the quality of color vision to varying degrees. This information is based on very limited research of color deficiency sites on line.
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.
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.

Are alleles made up of DNA?
All alleles contain DNA. They are the genes. An allele is one form of a gene. For example, the gene for flower color in pea plants has two alleles, one for purple flower color, and one for white flower color.
