What Is It Called When A Trait Is Determined By Multiple Genes? A polygenic trait is one whose phenotype is influenced by more than one gene. Traits that display a continuous distribution, such as height or skin color, are polygenic. What human traits are polygenic? Polygenic inheritance occurs when one characteristic is controlled by two
How Do Genes Determine The Traits Of An Organism? The traits an organism displays are ultimately determined by the genes it inherited from its parents, in other words by its genotype. … Variant copies of a gene are called alleles, and an individual’s genotype is the sum of all the alleles inherited from the parents.
What Does The Bell Curve Represent For A Polygenic Trait Give An Example? Polygenic inheritance often results in a bell shaped curve when you analyze the population (Figure below). … That means that most people fall in the middle of the phenotypic range, such as average height, while very few people are at the extremes,
What Is An Example Of Multifactorial Inheritance? Examples of multifactorial traits and diseases include: height, neural tube defects, and hip dysplasia. What is a multifactorial inheritance? Multifactorial inheritance is when more than one factor causes a trait or health problem, such as a birth defect or chronic illness. The main factor is genes. But the
