How many genes minimum is needed to determine a trait?
The least number is 2, however this is very rare. Most traits require many genes to produce a trait.
How many genes must interact to produce a trait?
It depends on the trait. Some are Mendelian traits where there is one dominant and one recessive allele. Some traits are governed by multiple alleles, like blood groups, and some traits are governed by polygenic inheritance where several sets of genes determine the trait, like height in humans.
The number of possible phenotypes for a given trait depends on how many what control the trait?
The number of possible phenotypes for a given trait depends on how many genes control the trait. Each gene may have multiple alleles that can interact to produce different phenotypes. Additionally, environmental factors can also influence the expression of these genes, further increasing the diversity of possible phenotypes.
In plants and animals does an offspring usually inherit at least two genes for a trait?
YES
What type two or more genes control a trait?
Polygenic inheritance is when two or more genes interact to control a trait. Each gene contributes to the phenotype in an additive manner, resulting in a continuous range of variations for the trait. Examples include human height and skin color.
Can a single gene control a single trait.?
It was once believed that one gene controls one trait, so it is possible. Currently, the belief is that one gene can interact with other genes to control a trait, and that one gene can control more than one trait.
What trait is is expressed when two diffrent genes for the same trait are present?
A dominant trait is expressed when two different genes for the same trait are present.
What is the number of genes that usually determines a trait?
the number of genes that usually determine a trait
What trait did Mendel identify in certain genes?
Mendel identified the trait of dominance in certain genes.
What is a trait that is determined by ones genes?
domanant trait
Why do some traits exhibit a large number of phenotype?
some human traits show a large number of phenotype because the traits are controlled by many genes. The genes act together as a group to produce a single trait
What kind of trait is present when many different genes different genes control a single trait such as skin color?
Polygenic trait.
