Human height is typically determined by polygenic inheritance, where multiple genes contribute to the phenotype, along with environmental factors. This results in a continuous range of heights in a population. This pattern of inheritance contrasts with Mendelian inheritance, where traits are controlled by a single gene.

What inheritance pattern best explains how genes influence human height?
Human height is influenced by multiple genes, making it a polygenic trait. The pattern of inheritance is more complex than simple Mendelian traits, as height is continuously variable and influenced by environmental factors as well. This fits with the idea of polygenic inheritance.
What type two or more genes control a trait?
Polygenic inheritance is when two or more genes interact to control a trait. Each gene contributes to the phenotype in an additive manner, resulting in a continuous range of variations for the trait. Examples include human height and skin color.
What would be your clue that a character would have polygenic inheritance pattern?
Well, honey, if you see a trait that's controlled by multiple genes, each with small effects, then you might be dealing with polygenic inheritance. So, keep an eye out for characteristics like height or skin color that show a wide range of variation in a population. And remember, genetics can be a real mixed bag, just like my collection of ex-husbands.
How does polygenic inheritance differ from Mendelian inheritance?
polygenic inheritance is when more than one genes are responsible for a character/phenotype. for example human skin color. if one want to draw a pedigree for that, he will not be able to succeed. although individual genes at molecular level is inherited according to mendel's laws. and mendelian inheritance simply follows mendels laws. also the character is controlled by one gene only. for example pea plant height.
When a trait has more than two alleles how is the trait inherited?
When more than two alleles are involved in the inheritance of a trait, it is called polygenic inheritance. Many quantitative characters have polygenic inheritance. Inheritance of blood groups is an example of polygenic inheritance in human being.When more than two alleles are involved in the inheritance of a trait, it is called polygenic inheritance.

Why is human height an expection to mendels principles of heredity?
Human height is governed by polygenic inheritance, which means that more than one gene determines a person's height.
Many human traits such as eye color and height are controlled by?
Polygenic Inheritance
How many genes account for human height?
55 orthologous genes are associated with human height

Why is human height an exception to mendel?
Human height is a polygenic trait, meaning it is influenced by multiple genes rather than just one. This leads to a continuous range of heights in the population rather than distinct discrete variations, making it more complex than the simple dominance and recessiveness seen in Mendel's pea plant experiments. Additionally, environmental factors such as nutrition and lifestyle can also influence human height, further complicating its inheritance pattern.
How is human?
an average human(height-5ft 10 in)weighs around seventy to seventy five kg...but weight can always differ...sometimes bones are heavy, sometimes muscle or extra fat account for the extra weight...the weight of a human depends on his height...

What is the chart of ancestry and trait used as a tool to study human patterns of inheritance?
A pedigree chart is used to study human patterns of inheritance.
What are the factors in human development?

Relative importance of biological inheritance and environmental factors in human development?
Both biological inheritance and environmental factors play significant roles in human development. While biological inheritance determines traits like eye color and height, environmental factors such as upbringing, education, and experiences shape personality, behavior, and cognitive abilities. The interaction between nature and nurture is complex and influences different aspects of development in unique ways.
