A polygenic trait is controlled by multiple genes, each contributing to the overall phenotype. These genes can interact in complex ways, often influenced by environmental factors, leading to a continuous range of phenotypic expressions. Examples of polygenic traits include height, skin color, and intelligence. The combined effects of various alleles from different genes result in the variability observed in these traits.
What else can I help you with?
What is used to describe a trait that is controlled by many genes?
A genetic trait.
What controls a polygenic trait?
two or more genes
What is a trait controlled by only one gene?
How nice you are. Yeah I was shocked too when I found out.
What carrier of a trait controlled by a allele does not express the trait?
A carrier of a trait controlled by a recessive allele possesses one copy of the recessive allele and one copy of the dominant allele. This means that they do not express the trait associated with the recessive allele because the dominant allele masks its effect. However, the carrier can pass the recessive allele to their offspring, who may express the trait if they inherit two copies of the recessive allele.
If a study of several pedigrees demonstrated that two parents are normal but their daughters and sons express a trait then the trait is controlled by what?
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.
