Polygenic offspring refer to individuals whose traits are influenced by multiple genes, rather than a single gene. This results in a continuous range of phenotypes for certain characteristics, such as height, skin color, or intelligence, rather than discrete categories. The combined effects of these various alleles create a more complex inheritance pattern, often influenced by environmental factors as well. Such traits are typically studied in the context of quantitative genetics.
What else can I help you with?
How is polygenic inheritance difference from the patterns describe by mendel?
Polygenic inheritance includes traits coming from one source. Mendel described traits as dominant or recessive and that determination created the charts determining the offspring outcome.
How genes affect characteristics?
It is a polygenic character
Traits that are shaped by many genes are called what?
Traits that are produced by the interaction of several genes are called polygenic traits. Examples of polygenic traits are height and skin color.
What controls a polygenic trait?
two or more genes
When traits do not appear according to the expected ratio in offspring what may have occured?
When traits do not appear according to the expected ratio in offspring, it could be due to genetic linkage, incomplete dominance, codominance, polygenic inheritance, epistasis, environmental factors, or genetic mutations. Additionally, errors during meiosis, such as non-disjunction or crossing over, can also lead to unexpected ratios of traits in offspring.

Is breast cancer codominant or polygenic?
POLYGENIC!
What occurs when a group of gene pairs act together to produce a single trait?
Polygenic Inheritance
Traits that are shaped by many genes are called what?
Traits that are produced by the interaction of several genes are called polygenic traits. Examples of polygenic traits are height and skin color.
What is trait called when it is controlled by more than one gene?
Polygenic Traits
A cross of a black chicken with a white chicken produces all blue offspring this type of inheritance is known as?
This cross of a black chicken with a white chicken producing an all black and white speckled offspring is an inheritance known as co-dominant inheritance.
True or false height is not a polygenic trait?
false, height is a polygenic trait
Are polygenic genes dominant genes?
Polygenic genes are usually dominant genes.
What controls a polygenic trait?
two or more genes
Incomplete dominance occurs when a group of gene pairs acts together to produce a single trait?
yes that is true. the classic example is a red flower (RR) and a white flower (rr). if they produce offspring that are Rr, the offspring will be pink. R is not dominant and r is not recessive; they are incompletely dominant and combine to form a new phenotype. ^actually, that's not the right answer to the question; the answer is "NO." polygenic inheritance occurs, not incomplete dominance. incomplete inheritance? really? The answer is polygenic inheritance
What is the opposite of polygenic trais?
The opposite of polygenic traits is monogenic traits. Polygenic traits are determined by the interaction of multiple genes, while monogenic traits are controlled by a single gene.
