Difference between dominant traits and recessive traits..

Dominant traits are those traits which are expressed even in the presence of one copy of an allele for a particular trait in the gene. For example: Yy shows the dominant trait for yellow color of seed. Seed is yellow even when single copy of dominant allele i.e. Y is present. 

Recessive traits are those that are expressed only when two copies of an allele are present in the gene. For example: yy shows the recessive trait for green colour of the seed. It is expressed only when both the alleles are recessive i.e. y.

when the two genes are for different traits. the trait which expresses itself is called dominant trait and the trait which does not express itself is called recessive trait.

dominant trait can express itself even when there is a singlee copy of it while for the recessive trait to be expressed both the genes should be for the recessive trait

Eg-dominant trait-T

recessive trait-t
