Traits
Traits (scientifically known as phenotypes)
A very simple way to understand the two is this: phenotype is what you see and genotype is what genes are there. Phenotypes are expressed genes and genotypes include recessive genes that are not seen.
because it dominates the phenotype
The outward expression of genetic traits are called phenotypes. Phenotypes expression include recessive and dominant genes such as eye and hair color.
When genes are expressed, the result is called phenotype. What is actually in all the genes (some are recessive) is called the genotype.
The dominant gene will always "cover up" the recessive gene, although there are instances of codominance, in which both phenotypes will be displayed, because one gene is not completely dominant over the other. There is also what is called 'incomplete dominance', when the actual phenotype is somewhere between the two.
Mutation occurs, if a mutation is recessive it is not expressed in the phenotype, if however it is dominant when passed on in the offspring it is expressed in the phenotype.
Inactive alleles (usually called recessive) are not fully expressed in the phenotype of the organism.
If an individual has one recessive allele and one dominant allele, they are known as heterozygous. The dominant trait will be expressed.
An allele whose characteristic phenotype is masked by the presence of a second allele is called recessive when used in reference to that second allele.
i think the answer your lokking for is recessive Recessive is when you have a trait in your genome but it doesn't show in your physical appearance
