If you mean an allele, then I know that the attached/hanging earlobe, the ability to taste ptc paper, dimples, chin fissures, freckles, human blood type A,B,O,AB without the rh factor is controlled by a single allele, there are three genes in this allele but only a pair is present in a human. Example A gene and B gene = AB blood. The RH factor may be another trait controlled by a single alele but I am not sure.

What traits in the human body are controlled by a gene?
Traits controlled by a single gene areAbility to roll the tongueFree ear lobeHitchhikers ThumbBent little fingerWidow's PeakDimpled ChinMid-Digital HairPigmented irises
What is one difference between single gene trait and a polygenic trait?
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
How many genes are needed to represent a trait?
It depends on the trait. Some traits exhibit simple Mendelian heredity, being governed by only one gene. However, many traits are governed by more than one gene, which is called polygenic inheritance.
Are studies in twins more important in understanding single gene traits or quantitative traits?
Studies in twins more important in understanding quantitative traits.
What does pleiotropy mean?
Pleiotropy occurs when one gene influences multiple, seemingly unrelated phenotypic traits (those you see). A series of defects that affect multiple systems but is caused by one defective gene.
What is the difference between single-gene traits and complex traits?
Single gene diseases only effect one typeof gene where im a complex genetic disease many genes are effected. An example of a single gene diseas is sickle cell anemia. Cancer would be an eexample of a complex gene disease.

Much of what we know about single gene traits in humans is the result of studying?
Much of what we know about single gene traits in humans comes from studying pea plants.
Can a single gene can influence multiple traits?
yes
Are Human traits like eye color and height inherited by polygenic traits?
Human eye color is an inherited polygenic trait because it is controlled by more than one gene. Various eye color includes blue, green, amber, hazel, brown, and violet.
How are single-gene traits useful in studying human genetics?
Single-gene traits are useful in studying human genetics because they exhibit a clear inheritance pattern, making it easier to trace their transmission through generations. This allows researchers to identify the specific gene responsible for the trait and study its function and impact on human health. Additionally, single-gene traits can provide insights into genetic disorders and help in developing targeted treatments or interventions.
What is one difference between single gene trait and a polygenic trait?
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
Which of the following are true. 1.single gene can control a single trait 2.single gene can influence multiple traits 3.single trait can be controlled by multiple genes?
All of them.
How many genes are needed to represent a trait?
It depends on the trait. Some traits exhibit simple Mendelian heredity, being governed by only one gene. However, many traits are governed by more than one gene, which is called polygenic inheritance.
What is gene shuffling?
Gene shuffling is when the natural trait of a single phenotype favours over the extreme traits over the intermediate.
Are studies in twins more important in understanding single gene traits or quantitative traits?
Studies in twins more important in understanding quantitative traits.
When a group of gene pairs act together to produce a single traits?
Polygenic Inheritance
