Height is a trait that can be influenced by both inheritance (genetics) and environmental factors such as nutrition and overall health. While genetics plays a significant role in determining a person's potential height, environmental factors during childhood and adolescence can also impact growth and final height.
What else can I help you with?
Is diabetes an example of a dominant or recessive trait in genetic inheritance?
Diabetes is not a simple genetic trait like dominant or recessive. It is a complex condition influenced by multiple genes and environmental factors.
What is the least prevalent mode of inheritance?
Polygenic inheritance is the least prevalent mode of inheritance because it involves multiple genes contributing to a single trait and is influenced by environmental factors, making it more complex and less common than other simpler modes like Mendelian inheritance.
Is diabetes a sex-linked trait?
No, diabetes is not a sex-linked trait. It is a complex condition influenced by a combination of genetic and environmental factors.
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.
Inheritance of stature height in humans is due to what?
Inheritance of stature height in humans is primarily influenced by multiple genes, with contributions from both parents. It is considered a polygenic trait, meaning that the phenotype results from the interaction of several genes. Additionally, environmental factors can also play a role in determining an individual's final height.
What is the condition called when there are many genes that affect a trait which are susceptible to changes due to the environmental factors?
This condition is known as polygenic inheritance. It involves multiple genes contributing to a trait, and the expression of these genes can be influenced by environmental factors. The combination of genetic and environmental influences leads to a wide range of variation in the trait.
Is diabetes an example of a dominant or recessive trait in genetic inheritance?
Diabetes is not a simple genetic trait like dominant or recessive. It is a complex condition influenced by multiple genes and environmental factors.
What is the least prevalent mode of inheritance?
Polygenic inheritance is the least prevalent mode of inheritance because it involves multiple genes contributing to a single trait and is influenced by environmental factors, making it more complex and less common than other simpler modes like Mendelian inheritance.
What is a trait that is overridden by another trait?
Eye color is an example of a trait that is typically determined by genetic inheritance, but can also be temporarily influenced by wearing colored contact lenses. This demonstrates how environmental factors can override genetic traits.
Is diabetes a sex-linked trait?
No, diabetes is not a sex-linked trait. It is a complex condition influenced by a combination of genetic and environmental factors.
Is shoe size a mendelian trait?
No, shoe size is not a Mendelian trait because it is influenced by multiple genes and environmental factors. It is considered a polygenic trait, meaning it is controlled by more than one gene, making it more complex than the simple Mendelian inheritance patterns.
Having the same genes for a specific trait?
Having the same genes for a specific trait means that individuals possess identical copies of the gene responsible for that trait. This may result in similar physical characteristics or behaviors. It can be influenced by both genetic inheritance from parents and environmental factors.
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.
How can enviromental factors influence a trait?
Complex traits are those that are influenced by more than one factor. The factors can be genetic or environmental.
What does it mean when a trait is non-Mendelian?
A non-Mendelian trait refers to genetic characteristics that do not follow the typical patterns of inheritance described by Gregor Mendel, such as complete dominance, segregation, and independent assortment. These traits may exhibit complex inheritance patterns, including incomplete dominance, codominance, polygenic inheritance, or environmental influences. Non-Mendelian inheritance can lead to a range of phenotypes that are not easily predictable based on Mendelian principles. Examples include traits like skin color and height, which are influenced by multiple genes and environmental factors.
Inheritance of stature height in humans is due to what?
Inheritance of stature height in humans is primarily influenced by multiple genes, with contributions from both parents. It is considered a polygenic trait, meaning that the phenotype results from the interaction of several genes. Additionally, environmental factors can also play a role in determining an individual's final height.
When the expression of a trait is determined by many different influences the trait is said to be?
When the expression of a trait is determined by many different influences, the trait is said to be polygenic. Polygenic traits are influenced by multiple genes, often interacting with environmental factors, leading to a continuous range of phenotypes. Examples include height, skin color, and intelligence, which illustrate the complexity of inheritance and expression in such traits.
