What is Polygenic Inheritence?
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 certain plant has a color that can range from green to yellow. Some plants are very green and some are very yellow but most are in-between. What is most likely true about this trait?
Several different genes control height
What are non-mendelian trait?
Non-Mendelian traits are:A trait with no clearly dominant alleleA trait with four allelesA trait controlled by many genes
What is the term that refers to the determination of a given trait that is a result of the interaction of many genes?
Polygenic inheritance refers to the determination of a trait that is influenced by the interaction of multiple genes. These genes can have additive or synergistic effects on the phenotype, resulting in a continuous range of variations for the trait. Examples of polygenic traits include height, skin color, and intelligence.
What is the 4 exceptions to Mendel's principles?
The blood type in humans
What is it called when three or more contrasting genes control a trait?
When three or more contrasting genes control a trait, it is called polygenic inheritance. This type of inheritance involves multiple genes interacting to influence a single trait, resulting in a continuous distribution of phenotypes in a population.
What Type AB blood having 2 genes dominant for a trait is an example for?
codominance
The height of a type of plant has a normal distribution some plants are tall and some are short but most are in between what is most likely true about this trait?
Several different genes control height

The concept that one type of trait will be more likely to be seen in offspring is part of the principle of?
The concept that one type of trait will be more likely to be seen in offspring is part of the principle of inheritance, specifically known as Mendelian genetics or Mendel's laws of inheritance. These laws describe how traits are passed from parent to offspring through the transmission of genes.
How many genes for a trait?
A trait is any gene-determined characteristic and is usually determined by more than one gene, therefore the exact amount depends on the specific gene. However, the number of genes in the genome varies from species to species. More complex organisms tend to have more genes. Estimates of the number of human genes, by contrast, range from 25,000 to 30,000.
