Dominant Traits.
Polygenic inheritance
Humans typically have two alleles for each gene, one inherited from each parent. These alleles can be the same (homozygous) or different (heterozygous), and they determine various characteristics. However, for traits controlled by multiple genes, the total number of alleles can vary significantly. Overall, the combination of alleles contributes to the diversity of traits in individuals.
The trait received is recessive.
The genes are homogyous dominate.
In humans, alleles for each gene are inherited from both parents, with each parent contributing one allele for each gene. This means that individuals have two alleles for each gene, one inherited from the mother and one from the father. The combination of these alleles determines the individual's traits and characteristics.
By sexual reproduction the parental alleles through gametes are inherited in the subsequent generation
Typically, traits with three different phenotypes are inherited by a single gene with multiple alleles. In this case, each allele controls a different phenotype. Examples of traits with multiple alleles include human blood type (A, B, O) and eye color (blue, brown, green).
Polygenic inheritance
Multiple alleles are "the existence of more than two alleles (versions of the gene) for a genetic traits. Polygenic traits are "[characteristics of organisms that are] influenced by several genes." So multiple alleles are more than two alleles for one trait, and polygenic traits are one trait that is influenced by multiple genes. This information came from my biology textbook, "Biology: Principles and Explorations" by Holt, Rinehart, and Winston.
Alleles are different forms of a gene that can be inherited from each parent. They contribute to the inheritance of traits by determining the specific characteristics an individual will have. Each trait is controlled by one or more alleles, with dominant alleles typically masking the effects of recessive alleles. The combination of alleles inherited from both parents determines an individual's genotype and ultimately their phenotype, or observable traits.
Multiple alleles are genes that have more than two alleles. An example of this would be blood types, with ABO as three separate alleles.Polygenic traits are traits whose phenotype rely on alleles from different genes. An example of this would be hair type, which relies on genes from different parts of chromosomes.The main difference is that multiple alleles are genes with 3 or more alleles; polygenic traits do not necessarily have more alleles, but they rely on on multiple genes.
The inherited combination of alleles is known as the offspring's genotype. It determines the genetic makeup of an individual based on the alleles inherited from each parent. The genotype influences the phenotype, or the observable traits of an organism.
Alleles are genes that exist in multiple forms.
The trait received is recessive.
The genes are homogyous dominate.

Traits controlled by a gene with multiple alleles can vary in terms of expression or phenotype. For example, human blood type (A, B, AB, O) is controlled by a gene with multiple alleles. The different alleles can result in different phenotypes (A, B, AB, O) for the same trait.
