In simple Mendelian genetics, there may be several alleles (variations) for a given trait. since organisms generally have two pairs of chromosomes, they have two alleles. A dominant allele is one that when it is present, always shows itself. A recessive allele only shows when there are two copies of the recessive allele. For example, suppose brown hair is dominant and black hair is recessive. If there are any copies of the brown hair allele, the person's hair will be brown. A person's hair will be black only if they have two copies of the black hair allele. In reality, genetics is much more complicated than simply dominant and recessive as many genes may influence one trait.

What makes a dominant allele different from recessive Allie?

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.


If a gene has one completely dominant allele and one recessive allele how many different traits can these alleles produce?

A gene with one completely dominant allele and one recessive allele can produce two different traits in a population. Individuals with two dominant alleles (homozygous dominant) and those with one dominant and one recessive allele (heterozygous) will exhibit the dominant trait, while only individuals with two recessive alleles (homozygous recessive) will display the recessive trait. Therefore, the two traits produced are the dominant trait and the recessive trait.


A living thing with a dominant and recessive gene for a trait?

A living thing with a dominant and a recessive gene for a trait is heterozygous. This individual will display the dominant phenotype for that trait but may have offspring that display the recessive trait.


What term describes an individual that has a dominant and a recessive allele for a trait?

The term for an individual with a dominant and a recessive allele for a trait is "heterozygous." This means they have two different alleles for a specific gene, with one being dominant and the other recessive.


What is the name given to the weaker trait that can be covered up by the dominant trai?

The recessive gene - less stronger than the dominant one.

When does a recessive trait dominant over a dominant trait?

A recessive trait cannot be dominant over a dominant trait. Dominant traits are always expressed over recessive traits in heterozygous individuals because they mask the expression of the recessive trait.


What type of trait prevents the other type from being seen?

A recessive trait. When a recessive allele is with a dominant allele, only the dominanate trait can be seen.

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 difference between a dominant trait and a recessive trait?

A recessive trait is a trait that is not shown or expressed physically but is retained within the persons genes, whereas a dominant trait is a trait which opresses the recessive trait and is prodominantly shown or expressed physically. For example it is possible for two red-haired parents, both with recessive dark haired genes, to have a dark haired child. they must both have the recessive gene or the dominant gene of red - hair will be expressed in the child
