Some genes also work to produce a single trait together. Order of dominance: brown > green > blue. How many genes must interact to produce a trait See answers (1) Ask for details ; Follow Report Log in to add a comment ... for a total of 46 chromosomes. A trait is any gene-determined characteristic and is usually determined by more than one gene, therefore the exact amount depends on the specific gene. In (b), QTNs directly affect Trait 1 and only influence Trait 2 through Trait 1. 1. Multiple gene pairs may interact to produce a single phenotype.

A single gene may have multiple possible variations, or alleles.

First Reason: Monogenic Traits Are Rare. This is a very large number, but it makes sense because height is a compilation of the lengths of many different body parts, such as leg bones, the torso, and even the neck. Second, the protein may be an enzyme that catalyzes one of the chemical reactions of the cell. Most traits are affected by many genes, and most genes are involved in the development of multiple traits. Top Answer. This is largely because the mutations in these genes don't actually mirror the gene networks responsible for the characteristics that present in people with the disorder. Asked in Genetics Which is a non-Mendelian trait? The way our genes and environment interact to produce a trait can be complicated. Today, it is possible to measure minuscule effects of multiple genes and it is well understood that the "one gene/one trait" paradigm is largely incorrect. How many genes must interact to produce a trait See answers (1) Ask for details ; Follow Report Log in to add a comment Answer 1. lucasnarutobemdez. Many times, an allele may be dominant over another allele for that trait. Polygenic inheritance process by which several genes interact to produce a certain trait; responsible for most important traits, an addictive effect of two or more genes on a single phenotypic character (the converse of pleitropy where a single gene affects several phenotypic characters) e g skin color In. Polygenic Traits: Definition, Example & Facts. Do you think skin color is a polygenic trait? Many of the observable characteristics of an organism are influenced by more than one gene, and the corresponding polygenic inheritance becomes complex. In complementary gene action, the products of two non-allelic genes act in a linear pathway to produce a single end product that determines the phenotype. Traits that are caused by the interaction of many genes are said to be? 3. By Bert Markgraf. Asked in Genetics. When a sperm and egg fuse, their 23 chromosomes pair up and create a zygote with 23 pairs of chromosomes.

Share . Quantitative trait nucleotides (QTNs) that occur in genes that regulate multiple phenotypes can cause correlated trait changes (a). The net outcome of the reading of a gene is that a protein is made that generally has one of two basic functions, depending on the gene. Two alleles for a given gene in a diploid organism are expressed and interact to produce physical characteristics. ... require many genes to produce a trait. But single-gene "knock-out" mice, in which a specific gene is lost, haven't really been able to show the role individual genes play in Williams syndrome. some human traits show a large number of phenotype because the traits are controlled by many genes. In duplicative gene action, the products of two non-allelic genetic loci act in parallel pathways, each of which can produce the same phenotype. Print . Tweet .

While this is not, strictly speaking, a case of gene interactions, it can account for a range of phenotypes that can resemble the results of gene interactions. douwdek0 learned from this answer Answer:Every human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. Recall the phenotypic inheritance pattern for Mendel’s dihybrid cross, which considered two non-interacting genes—9:3:3:1. Examples are microtubule, muscle, and hair proteins. Updated May 08, 2019 .
Production of a phenotype that is intermediate between the two homozygous parents. Wiki User. ***polygenetic inheritance. Some genes work with other genes to make a trait. It takes several separate genes to determine how tall you will be. Load More. There are several patterns that account for the inheritance of traits. Explain your reasoning, and be as specific as possible.
In this figure, we show how this can arise due to polymorphisms that alter the function of a single protein. The genes act together as a group to produce a single trait Asked in Biology , Genetics

Multiple genes interact to determine these traits, which is why there is such diversity. Fur has 1 ... At least _____ genes must interact to produce a trait. Polygenic traits are produced by two or more genes. Many genes may interact to produce one trait. A genome is all the genetic information of an … Many genes have more than two alleles. Monogenic Trait Variability: Multiple Alleles at a Single Gene Locus Many genes have more than two alleles, and not all the alleles have equal dominance/recessiveness. First, the protein may be a structural protein, contributing to the physical properties of cells or organisms. Some traits are caused by abnormal genes that are inherited or that are the result of a new mutation.

The interaction of two genes can produce nine different phenotypes for a single trait.
