dominant alleles will always overrule recessive alleles. So if you have any dominant allele in the phnotype or geneotype, the dominant trait will be expressed. For example, since black fur is dominant to brown fur on mice, if two black mice mate, at least part of their offspring will have black fur. If they are heterozygous for black, though, that's when a brown mouse offspring may be possible, but there would always be more black offspring than brown offspring. parents offspring (4) Bb x Bb --> BB, Bb, Bb, bb BB x Bb --> BB, BB, Bb, Bb BB x BB --> BB, BB, BB, BB BB x bb --> Bb, Bb, Bb, Bb Bb x bb --> Bb, Bb, bb, bb anything with a capital B would be black while "bb" is the only brown.

Dominant: dark hair, curly hair, detached earlobes

Recessive: red hair, albinism

There are infinite examples. :3

NOTE: Not sure about the hair stuff, and there are much better examples, though at least albinism is well known. Contrary to popular belief and what Hugh Laurie says on House eye colour is a complex trait, like height.

In pea plants, tall height is dominant and short height is recessive. The tall allele is represented with a capital T, while the short allele is represented by a lowercase t. The genotype TT represents the homozygous dominant condition, while Tt represents the heterozygous condition. Both TT and Tt will produce the tall phenotype. The tt genotype represents the homozygous recessive condition and will produce the short phenotype.

An example of a dominant allele being expressed is when a human has free earlobes, rather than attached earlobes (a recessive trait).

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.

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.


What is recessive and dominant mean?

I am pretty sure the recessive and dominant alleles you are talking about are covered in Biology. Recessive alleles are basically alleles that are received from both parent's DNA that are carries, (dd). However, dominant alleles are (exactly what it says) always expressed. If there is one dominant allele and one recessive allele the dominant allele overpowers the recessive. (DD) and (Dd)overpowers (dd).


What makes a dominant alleles different from a recessive alleles?

A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.


Is a situation in which a dominant allele completely masks a recessive allele for a gene.?

If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
