the number of genes that usually determine a trait
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.
Eye color is a physical trait that is determined by inherited genes. The specific combination of genes inherited from parents determines the color of an individual's eyes.
A genetic locus is the specific location on a chromosome where a particular gene is located. It serves as a unit that determines the expression of a specific trait due to the presence or absence of alleles at that locus.
The number of phenotypes produced for a given trait depends on how many genes control the trait.
A specific trait is determined by a combination of genetic factors and environmental influences. Genes provide the blueprint for traits, but factors like diet, lifestyle, and experiences can also play a role in shaping how traits develop. Additionally, epigenetic factors can impact how genes are expressed, further influencing specific traits.
Phenotypes
Variations
The least number is 2, however this is very rare. Most traits require many genes to produce a trait.

The probable number of genes involved in polygenes can be calculated using statistical methods such as quantitative trait loci (QTL) mapping or genome-wide association studies (GWAS). These methods analyze the genetic variations and their effects on a particular trait to estimate the number of genes contributing to its polygenic nature. The specific number of genes involved can vary depending on the complexity of the trait and the techniques used for analysis.
A genotype is a group of genes that influence a given trait, whereas a phenotype in this case would be that trait. An example of a sentence using the word "genotype" is "The different genes you inherit from your parents make up the genotype that determines your eye color. "
The trait will show a large number of variations or phenotypes due to the interactions between multiple genes. This is known as polygenic inheritance, where each gene contributes a small effect to the overall phenotype.
