What is the condition called when there are many genes that affect a trait which are susceptible to changes due to environmental factors?
Multifactorial trait
Is cleft lip a chromosomal error or a multifactorial trait?
Cleft lip is considered a multifactorial trait, meaning it is caused by a combination of genetic and environmental factors rather than a chromosomal error. It can be influenced by both genetic predispositions and exposure to certain environmental factors during pregnancy.
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.
What is multifactorial transmission?
This occurs when environmental factors interact with genetic factors to produce traits. The term multifactorial means many factors. Traits that involve multiple genes and complicated patterns of inheritance are said to be exhibiting multifactorial transmission.
What is multifactorial polygenic threshold theory?
Multifactorial polygenic threshold theory proposes that complex traits are influenced by both genetic and environmental factors. It suggests that multiple genes contribute to the expression of a trait, and a certain threshold of genetic and environmental factors must be reached to manifest the phenotype. This theory is often used to explain the inheritance of complex traits such as height, intelligence, and susceptibility to diseases.
Is familial hypercholesterolemia a multifactorial defect?
homosexual
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 health as a multifactorial phenomenon?
Health as a multifactorial phenomenon involves several factors. These factors include economic, socio-cultural, and environment. It also includes political factors which involve political will and empowerment.
What cause Goldenhar Syndrome?
causes are Multifactorial but there may be due to gentic component
Which condition follows a multifactorial pattern of inheritence?
Congenital heart defects, cleft lip and palate, and Type 2 diabetes are examples of conditions that follow a multifactorial pattern of inheritance. This means they result from a combination of genetic and environmental factors interacting together.
Is skin color a quantitative trait?
It is indeed. Quantitative traits suggest that the traits are polygenic, which means that the trait is influenced by more than one gene and skin color is influenced by 3 genes (6 alleles). Skin color is also a multifactorial trait because there are also many environmental factors that change skin color, such as exposure to sunlight.
Does genetic addiction appears to be polygenic and multifactorial?
Not entirely. Don't forget that there are father and mother genetic factors.
