What is dominant in biology example?
Dominant alleles show their effect even if the individual only has one copy of the allele (also known as being heterozygous?). For example, the allele for brown eyes is dominant, therefore you only need one copy of the ‘brown eye’ allele to have brown eyes (although, with two copies you will still have brown eyes).

What is dominant and recessive alleles?
The most common interaction between alleles is a dominant/recessive relationship. An allele of a gene is said to be dominant when it effectively overrules the other (recessive) allele. Eye colour and blood groups are both examples of dominant/recessive gene relationships.
What is dominant and recessive in biology?
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.
What is recessive in biology?
Recessive refers to a type of allele which will not be manifested in an individual unless both of the individual’s copies of that gene have that particular genotype.
What is the difference between dominance and recessive?
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.

What are the different types of dominance in biology?
Related Biology Terms 1 Codominance – When two dominant alleles are expressed separately, in different areas of an organism. 2 Incomplete Dominance – When two dominant alleles are expressed equally, in every cell. 3 Recessive Allele – An allele that is completely masked phenotypically by a dominant allele.
