How nice you are.
Yeah I was shocked too when I found out.
If the trait is exhibited in the offspring of two normal parents, it suggests that the trait is a dominant one. This means that only one copy of the gene is needed for the trait to be expressed. Alternatively, the trait could be influenced by a de novo mutation that occurred in the germ cells of one of the parents.
No, the frizzle trait in chickens is not an example of pleiotropy. Pleiotropy refers to a single gene affecting multiple traits. However, the frizzle trait is controlled by a single gene that affects only one observable trait - the curliness of feathers.
A widow's peak is a V-shaped point of hair at the front of the head, and it is controlled by genetics. It is inherited as a dominant trait, meaning one copy of the gene from either parent can result in a widow's peak.
A trait with only two distinct phenotypes is more likely to be a single-gene trait. This is because single-gene traits are typically controlled by one gene, resulting in discrete phenotypes, such as dominant and recessive. In contrast, polygenic traits involve multiple genes and usually exhibit continuous variation, leading to a wide range of phenotypes rather than just two distinct categories.
This is known as a dominant trait. Dominant traits require only one copy of the gene to be expressed in an individual. The presence of one dominant allele is sufficient to display the trait, even if the individual also carries a different allele for the same gene.
Yes, if a trait is controlled by a dominant gene, it will be expressed regardless of the instructions of the corresponding gene in the other half of the pair. Dominant genes only require one copy to be expressed in the phenotype.
if its all controlled by one gene
How nice you are. Yeah I was shocked too when I found out.
Polygenic Traits
A single gene trait is a specific characteristic or phenotype that is influenced by the expression of a single gene. This means that the presence or absence of a particular trait is determined by variations in one specific gene. Examples include earlobe attachment, hair color, and tongue rolling.
A trait controlled by many genes
It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.
One gene controlled one trait within Mendel's study, but the sickle cell anemia effects more than one trait.
A non Mendelian trait can be controlled by one gene. When a trait is controlled by one gene it results in genetic disorders. Examples of disorders due to single gene inheritance - Huntington disease, Fragile-X syndrome.
