The colour of wheat seeds, or skin colour are common examples used in text books.
An allele is a type of gene that is hereditory. In fertilisation, an allele from both the father and mother are fused, this is multiple allele hereditory. Alleles influence many things, from hair colour to blood type. human blood typeshuman blood types
An allele that is masked by the dominant allele is called a recessive allele. When an individual has one dominant allele and one recessive allele, only the trait determined by the dominant allele will be expressed. The recessive allele will only be expressed if an individual has two copies of it (homozygous recessive).
I had this question on a test as a multiple choice so I know the answer is either genotype, heredity, allele or gene if that helps.
Dominant traits are traits that are expressed when an individual carries at least one copy of the dominant allele. These traits mask the expression of recessive alleles. For example, if an individual has one dominant allele for brown eyes and one recessive allele for blue eyes, they will have brown eyes because the dominant allele is expressed.
Blood types are an example of an inherited trait determined by specific genes on the chromosome.

The multiple allele system refers to a genetic system where a particular gene has more than two alleles present within a population. Each individual carries a maximum of two alleles for a gene, but the population as a whole may have multiple alleles. An example of this is the ABO blood group system in humans.

Multiple alleles means that for a specific locus on a chromosome there can be 3 or more forms of that gene (allele). Only one allele can be inherited because they are found on homologous chromosomes. Height is not a multiple allele because it is associated with many genes on several chromosomes (plus environmental factors) so this would be polygenic inheritance. Multiple allele trait is the ABO group. The allele for A B or O (3 alleles ) is found on the same locus, therefore only one of them could be inherited EXAMPLE: DNA

A dominant allele is the allele which expresses itself morphologically.for example;the dimple on your cheek.your mom has a dimple whereas your father doesn't have it .but you too possess it.then ,your mother's allele serves to be the dominant allele.
The different forms of a genes for a single trait are known as alleles there can be a dominate allele which always shows up when present and a recessive allele which only shows up when both alleles are recessive or there is no dominate allele
