What else can I help you with?
Much of what we know about single gene traits in humans is the result of studying?
Mendelian inheritance patterns in families and populations. By analyzing family pedigrees, researchers can track the transmission of specific traits from one generation to the next, helping to identify the genetic basis of various human phenotypes. Additionally, population studies and genome-wide association studies have further advanced our understanding of single gene traits in humans by identifying specific genetic variants associated with certain traits or diseases.
Traits controlled by two or more genes are called what?
Traits controlled by two or more genes are called polygenic traits. In polygenic inheritance, multiple genes work together to produce a particular phenotype, resulting in a wide range of possible variations. Examples include height, skin color, and eye color in humans.
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.
What are quantitative traits?
Quantitative traits refer to characteristics that are determined by multiple genes and environmental factors, resulting in a continuous range of phenotypes. These traits are typically measured on a numerical scale, such as height or weight. Quantitative genetics is the field of study that focuses on understanding the genetic basis of these complex traits.
What are genetically controlled?
Genetically controlled traits are characteristics or features of an organism that are determined by the genes they inherit from their parents. These traits can be influenced by multiple genes (polygenic traits) or a single gene (monogenic traits) and can be inherited in different ways, such as through dominant or recessive alleles. Examples of genetically controlled traits include eye color, height, and susceptibility to certain diseases.
What are some polygenic traits in humans?
Skin color, height, weight
Which of these humans traits is altered by variations in environment?
height
How does the range of phenotypes for single gene traits different from the range for polygenic traits?
ABO Single gene trait blood group alleles on humans. That is the variation, not much, and not much recombination. 3! = 6. There is posited to be at least 7 alleles for height, which is a polygenic trait. Hypothetical alleles, SMYDKECV 7! = 5040 different combinations of alleles in height polygenic traits.
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.
How does the range of phenotype differ between single-gene traits and polygenic traits?
Single gene traits are either one type or another,for example everyone is either (ABO System) group A,B AB or O with no intermediates - this shows discontinuous variation. In polgyenic traits, continuous variation is shown and there is a range with no discrete categories - height
Which describes a Mendelian trait A. Human height is controlled by many genes. B. There are many different skin colors for humans. C. Humans can have a variety of shoe sizes. D. Humans can have dimple?
D. Humans can have dimples describes a Mendelian trait. Mendelian traits are typically influenced by a single gene and exhibit clear dominant and recessive patterns of inheritance. In contrast, traits like height and skin color are polygenic, meaning they are controlled by multiple genes.
What are some example of dominant and recessive traits in humans?
Dwarfism is a dominant trait in humans.
Blood types in humans are an example of traits controlled by?
Multiple alleles
Traits controlled by two or more genes are?
Hello there! Traits controlled by two or more genes are for example skin color and height.

What traits that are controlled by more than 1 gene?
Breathing, for one. Mindfulness is another. Respiration is the best example of this when it is considered to be a single trait. There are many less complex instances, yet all are 'highly biochemically involved'.
What is an example of continuity?
Examples are body weight, height, or shape, reproductive rate, and various behaviour traits.
