genes and the environment
A mutation does not affect an organism trait for a reason. It is neutral which depends on the environment.
An organism with two like alleles for a trait is homozygous for that trait.
If the the trait is controlled by only one allele and the allele is completely dominant then once inherited the offspring with exhibit that phenotype
an organism that has two different alleles for a trait is heterozygous
A mutation in a gene can alter the functioning of the protein it codes for, leading to changes in the trait expressed by the organism. This can result in new traits, loss of function, or altered function of the protein, impacting the organism's phenotype.
An organism that has two different alleles for a given trait is referred to as heterozygous for that trait. For example, if one allele codes for a dominant trait and the other for a recessive trait, the dominant trait will typically be expressed in the organism's phenotype. This genetic variation can contribute to diversity within a population and may influence the organism's adaptability to its environment.
Non-allelic genes are genes located on different chromosomes that do not directly influence each other. They can affect the expression of a specific trait in an organism through independent pathways, leading to a combination of different genetic factors influencing the trait.
Acquired Trait
This could be called a trait (inheritance).
It is called the phenotype or phenotypic trait.
A recessive trait only appears in an organism when it is homozygous for that trait, meaning it has two copies of the recessive allele. This occurs when an organism inherits the recessive allele from both parents.
Three factors that affect an organism's traits are genetics (inherited DNA), environmental conditions (such as temperature or availability of resources), and interactions with other organisms (such as competition or symbiosis).
