The terms dominant and recessive describe the inheritance patterns of certain traits. That is, they describe how likely it is for a certain phenotype to pass from parent offspring. Sexually reproducing species, including people and other animals, have two copies of each gene.

What is the difference between dominant and recessive traits? Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.
Most human cells carry two copies of each chromosome, so usually have two versions of each gene. These different versions of a gene are called alleles. Alleles can either be dominant or recessive, which describes the way their associated traits are inherited.
Oct 23, 2018 · The main difference between dominant and recessive genes is that the dominant genes always express the dominant trait whereas the recessive genes express the recessive trait. Furthermore, the dominant genes are more likely to pass to the future generation while the recessive allele is less likely.
3 days ago · Typically, an individual who carries two copies of a dominant allele exhibits the same trait as those who carry only one copy. This contrasts to a recessive trait, which requires that both alleles be present to express the trait.
Autosomal dominant is one way that genetic traits pass from one parent to their child. When a trait is autosomal dominant, only one parent needs to have an altered gene to pass it on. Half of the children of a parent with an autosomal trait will get that trait.
If an allele is recessive, then the gene needs to have two copies (or be homozygous) to express the recessive phenotype. If an organism is a heterozygote, or has one copy of each allele type, then it will show the dominant phenotype.
