Traits that are controlled by more than one gene such as human height are referred to as . single-gene traits recessive traits polygenic traits dominant traits?
Traits that are controlled by more than one gene, such as human height, are referred to as polygenic traits. These traits result from the cumulative effects of multiple genes, leading to a continuous range of phenotypic expressions. In contrast, single-gene traits are determined by a single gene and typically exhibit discrete variations.
Would a trait that has only two distinct phenotype more likely be a single-gene trait or a polygenic trait?
A trait with only two distinct phenotypes is more likely to be a single-gene trait. Single-gene traits, also known as Mendelian traits, typically exhibit clear dominant and recessive alleles, resulting in two phenotypic expressions. In contrast, polygenic traits involve multiple genes and usually display a continuous range of phenotypes rather than just two distinct forms.
What is the phenotypic ratio for 121?
To determine the phenotypic ratio for a specific number like 121, more context is needed regarding the genetic cross or traits being studied. Typically, phenotypic ratios arise from specific genetic crosses, such as Mendelian inheritance patterns (e.g., a 3:1 ratio for a monohybrid cross). If you provide details about the traits and parental genotypes involved, I can help calculate the phenotypic ratio.
When two or more forms of the gene for a single trait exist some forms of the gene my be?
When two or more forms of a gene for a single trait exist, these different forms are called alleles. Some alleles may be dominant, which means they will express their traits even when only one copy is present, while others may be recessive, requiring two copies for their traits to be expressed. This variation in alleles contributes to the genetic diversity observed in populations. Additionally, some alleles may be co-dominant or exhibit incomplete dominance, leading to a range of phenotypic expressions.
When more than one pair of genes control a trait it is considered?
When more than one pair of genes controls a trait, it is considered a polygenic trait. Polygenic traits are influenced by multiple genes, each contributing to the overall phenotype in a cumulative manner. Examples include traits like height, skin color, and eye color in humans. This complexity often results in a continuous range of phenotypic expression.

What is a trait called when it is controlled by more than on gene?
A trait that is controlled by more than one gene is called polygenic. This means that multiple genes contribute to the expression of the trait, leading to a continuous range of phenotypic variation. Examples of polygenic traits include height, skin color, and intelligence.
Would a trait that has only two distinct phenotype more likely be a single-gene trait or a polygenic trait?
A trait with only two distinct phenotypes is more likely to be a single-gene trait.

In contrast, polygenic traits involve multiple genes and usually display a continuous range of phenotypes rather than just two distinct forms.
Can a single gene influence multiple traits?
Yes, a single gene can influence multiple traits through a phenomenon known as pleiotropy. This occurs when a gene's expression affects more than one phenotypic trait due to its role in multiple biological pathways. Pleiotropy can result in diverse and interconnected effects throughout an organism's development and physiology.

What type of gene causes traits that are more likely to occur?
a dominant gene.
What are traits called that are controlled by more than one gene?
They are called Polygenic Traits.
What is the difference between single-gene traits and complex traits?
Single gene diseases only effect one typeof gene where im a complex genetic disease many genes are effected. An example of a single gene diseas is sickle cell anemia. Cancer would be an eexample of a complex gene disease.
When two or more forms of the gene for a single trait exist some forms of the gene my be?
When two or more forms of a gene for a single trait exist, these different forms are called alleles.

This variation in alleles contributes to the genetic diversity observed in populations. Additionally, some alleles may be co-dominant or exhibit incomplete dominance, leading to a range of phenotypic expressions.
When a single trait is affected by more than one gene locus this called?
This is called polygenic inheritance. Multiple genes contribute to the expression of a single trait in polygenic inheritance, resulting in a continuum of phenotypic variation. Traits like height, skin color, and intelligence are influenced by multiple gene loci.
What is a trait is called when it is controlled by more than one gene?
Polygenic Traits
When more than one pair of genes control a trait it is considered?
When more than one pair of genes controls a trait, it is considered a polygenic trait.
