Dominant is an allele that will always be expressed in a heterozygous individual.

Recessive on other hand are traits that will only be expressed in a homozygous condition.

Organisms receive one allele for each trait from each parent, thus you have two alleles for each trait.

the allele that carry the trait which is expressedin f1 progeny is called dominant allele and the allele which carry trait that is not expressed in f1 progeny is called recessive allele

dominant-appears in first generation

recessive-seems to disappear

A dominant allele will be expressed over a recessive allele if both are present.

For example:

B - black fur (dominant)

b - white fur (recessive)

An individual with Bb will have black fur because this is the dominant allele.

What is the difference between a herezygous and a homozygous?

"Heterozygous" and "homozygous" are terms that refer to alleles, which, in genetics determine what trait, from which parent, will appear in the offspring. Alleles can be either Dominant or Recessive. Every organism has two alleles, which can both be dominant, both recessive, or one of each.So,If an organism heterozygous, it has one recessive and one dominant allele.If an organism is homozygous then both of its alleles are the same; you need to specify if they are homozygous recessive (both alleles are recessive) or homozygous dominant (both alleles are dominant).

Dominant alleles are shown by a capital letter and recessive alleles are lowercase letters.

What is gene pair consists of two dominant alleles or two recessive alleles?

A gene pair that consists of 2 dominant or 2 recessive alleles is considered homozygous dominant or homozygous recessive.

Dominant alleles :-)


How dominant and recessive alleles are represented in a Punnett Square?

Dominant alleles are written in upper case (i.e, 'A'), while recessive alleles are lower case (i.e, 'a')


How is recessive alleles different from dominant alleles?

You need two recessive alleles to get their trait, but only one dominant allele to get that trait. A dominant allele basically overrides a recessive one if they are together, but the recessive gene can show up in offspring.


What is the difference between dominant and recessive alleles on the basis of DNA?

Dominant alleles override recessive alleles. For instance, if there is both a dominant allele and a recessive allele present the dominant allele will be the trait that you end up with. If you have two recessive alleles, then you will have the recessive trait. :::::::::::::::brown eyes overrided blue eyes, because they are darker:::::::::::::::::: usually a darker color overpowered/override the lighter ones....i dont really know why but my science teacher said so......

How do dominant alleles recessive alleles differs?

Dominant alleles are the ones that show up in the phenotype. Recessive alleles do not unless both alleles are recessive, but can be passed on. For example: Tt , T=tall and t=short. Tall is dominant and short is recessive. You are tall and can pass on the short gene. Or, you can use black hair being dominant over red. Or, brown eyes being dominant over blue. Dominant can be seen on you and recessive can't.
