When multiple genes determine the phenotype of a trait, this is an example of polygenic inheritance. In polygenic traits, the combined effects of several genes contribute to the expression of a phenotype, leading to continuous variation in characteristics, such as height or skin color. This contrasts with traits determined by a single gene, which typically exhibit discrete categories.

What is a description for phenotype and example?
The phenotype is a physical characteristic that is expressed by the genes. ----- An example of a phenotype is human blood group.
What an organism looks as a result of its genes is called?
The physical appearance of an organism as determined by its genes is called its phenotype. The phenotype is the observable traits or characteristics of an organism, such as its color, shape, size, and behavior, resulting from the expression of genes.
Determines an organisms phenotype?
genes and environment
When can an organism phenotype be different from its genotype?
An organism's phenotype can differ from its genotype due to environmental factors, such as temperature, nutrition, and exposure to toxins, which can influence the expression of genes. Additionally, epigenetic modifications, which affect gene expression without altering the DNA sequence, can also lead to phenotypic variation. Moreover, certain traits may be influenced by multiple genes or interactions between genes, resulting in a phenotype that does not directly reflect the underlying genotype.
How does eye color pass to the young?
It is because of an inherited phenotype, a phenotype is the outward expression of genes. the source of the inherited phenotype is dependent upon whether mother or fathers genotype is consisting of dominant or recessive allele i.e a dominant allele if pair with a recessive will be the one inherited.

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 determins phenotype?
the genotypeThe genotype (genes) of an organism determines its phenotype (what it looks and acts like). The phenotype can also be slightly influenced by the organism's environment. For example, if a human inherits genes to be taller than average, but has poor nutrition as a child, he won't be as tall as his genes had coded.
What carries genes that determinethe sex of offspring?
2 sex chromosomes in male-xx in female-xy
How do you use genotype and phenotype in a sentence?
The genotype of an organism refers to its genetic makeup, while its phenotype relates to its observable traits. For example, a plant with the genotype for tall height may exhibit a phenotype of actually being tall in stature.
What are examples of a genotype and a phenotype?
Genotype relates to the genetic makeup of an individual, and refers to all the genes on your chromosomes, whereas phenotype refers to the physical attributes that exist as a result of the genotype. Taking eye colour as an example, your phenotype will be brown eyes, and your genotype will be the two genes (one from the sperm and one from the egg). Only one of these two genes (the dominant one) will contribute toward your phenotype.
How do genes make a phenotype?
They are expressed.
How does a gene contribute to the expression of a phenotype?
The combination of genes tell what phenotype will be projected
What an organism looks as a result of its genes is called?
The physical appearance of an organism as determined by its genes is called its phenotype. The phenotype is the observable traits or characteristics of an organism, such as its color, shape, size, and behavior, resulting from the expression of genes.
What is the general rule of thumb for a phenotype?
A phenotype is the observable physical or biochemical characteristics of an organism, which result from the interaction between its genetic makeup (genotype) and the environment. It is typically influenced by multiple genes and environmental factors, making it complex and variable.
What ultimately determines the phenotype of an individual?
The phenotype of an individual is ultimately determined by a combination of their genetic makeup (genotype) and environmental factors. Genes provide the instructions for building and maintaining an organism, while the environment can influence the expression of these genes. The interaction between genetics and environment shapes the physical and behavioral characteristics that make up an individual's phenotype.
What is it called when the phenotype is determined by more than two unlinked loci?
When the phenotype is determined by more than two unlinked loci, it is referred to as polygenic inheritance. This means that multiple genes at different loci contribute to the expression of a particular trait or phenotype.
