What else can I help you with?
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.
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.
A transgenic organism that has extra copies of a gene produces more of RNA the that is coded for by the gene?
In a transgenic organism with extra gene copies, there is typically an increase in the production of the corresponding RNA due to the additional gene copies being transcribed. This can lead to an elevated expression level of the gene's product, which could result in observable phenotypic changes in the organism.
What are the limitations of a punnett square as model of inheritance?
Punnett squares are limited in that they primarily illustrate the inheritance patterns of single traits governed by simple Mendelian genetics, overlooking more complex scenarios such as polygenic traits, epistasis, and gene interactions. They assume random mating and do not account for factors like environmental influences or mutations that can affect phenotypic outcomes. Additionally, Punnett squares can become unwieldy when dealing with multiple alleles or traits, making them less practical for predicting outcomes in more complex genetic scenarios.
What describes Mendelian traits?
Mendelian traits are:simple single traits controlled entirely by one genecaused by a gene with simple dominant and recessive allele formsA Mendelian trait would not involve more than one gene, nor would it involve genes with more than two allele forms.
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.
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.
What is a trait is called when it is controlled by more than one gene?
Polygenic Traits
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 more than one set of genes controls a trait?
genetic traits
What is more strongly inherited?
Traits or characteristics that are controlled by a single gene, such as blood type or certain genetic disorders, are typically more strongly inherited than traits that are influenced by multiple genes or the environment, such as height or intelligence. These single-gene traits are passed down in a predictable manner from parents to offspring.
A transgenic organism that has extra copies of a gene produces more of RNA the that is coded for by the gene?
In a transgenic organism with extra gene copies, there is typically an increase in the production of the corresponding RNA due to the additional gene copies being transcribed. This can lead to an elevated expression level of the gene's product, which could result in observable phenotypic changes in the organism.
Why are sex-linked traits more common in males?
Males normally have the dominat gene.
Are traits controlled by the interaction of two or more genes?
or one gene, all by its lonesome.
