Some traits are determined by the combined effect of more than one pair of genes also called polygenic, or continuous, traits. An exampleis human stature. The size of all of the body parts from head to foot determines the height of an individual. The sizes of all of these body parts are, in turn, determined by numerous genes. Human skin, hair, and eye color are also polygenic traits because they are influenced by more than one allele at different loci.

WHAT is single gene trait?
A single-gene trait is a phenotypic trait controlled by two homologous alleles.
What is strand of DNA that codes for a specific trait?
A gene is a strand of DNA that codes for a specific trait
What a trait looks like is a?
Phenotypes
What is a trait that is expressed even if only one gene for that form of the trait is inherited?
It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.
Dominant gene plus Dominant gene?
It would be definite that you have that gene or trait.
What is a trait that is determined by a gene found on one of the sex chromosomes?
A sex linked trait.
What is a physical trait determined by what type of gene?
The nucleus divedes
What is one difference between single gene trait and a polygenic trait?
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
What is a gene trait?
A single-gene trait is a phenotypic trait controlled by two homologous alleles.
WHAT is single gene trait?
A single-gene trait is a phenotypic trait controlled by two homologous alleles.
What is strand of DNA that codes for a specific trait?
A gene is a strand of DNA that codes for a specific trait
What is an XO genotype?
it means it has one gene from the dominant trait and one gene from the recessive trait
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.
Factors that control traits are called what?
A "trait" such as tall/short or round/shrivelled (in relation to pea plants Mendelian genetics) is determined by which allele or version of the gene is inherited by the offspring.
What a trait looks like is a?
Phenotypes
What gene that is always expressed and will produce a trait?
The gene that is always expressed and will produces a trait is a genetic statistic. This statistic is what is created when the gene is dominant.
What is a trait that is expressed even if only one gene for that form of the trait is inherited?
It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.
