A widows peak is controlled by one gene that is passed on from both parents. In this case lets say your parents both have a dominant allele for a widows peak
(A) so in that case, you would have a 100% chance of being born with one.
Non-Mendelian traits are:A trait with no clearly dominant alleleA trait with four allelesA trait controlled by many genes
A trait controlled by many genes
An inherited trait is typically determined by multiple genes working together. The exact number of genes involved can vary depending on the trait. In many cases, dozens to hundreds of genes may contribute to a single inherited trait.
The trait of an organism is controlled by its genes, which are segments of DNA that provide instructions for building and maintaining the organism. Genes influence various traits such as physical appearance, behavior, and susceptibility to diseases. Environmental factors can also play a role in the expression of traits.
Polygenic inheritance refers to the inheritance of a trait that is controlled by multiple genes, each with a small effect on the phenotype. Traits such as height, skin color, and intelligence are often influenced by multiple genes working together. This type of inheritance results in a continuous range of phenotypes rather than distinct categories.

A genetic trait.
Trait that is controlled by many genes and is also influenced by the environment.
a trait controlled by many genes
The number of phenotypes produced for a given trait depends on how many genes control the trait.

Multiple gene inheritance. Sree
Inheritance in which more than one gene pair affects the appearance of a particular trait. Polygenetic inheritance refers to the non-Mendelian form of inheritance in which a particular trait is produced by the interaction of many genes.
some human traits show a large number of phenotype because the traits are controlled by many genes. The genes act together as a group to produce a single trait
