Question

What do you mean by dominant and recessive alleles

Answer 1

Dominant alleles - the allele which expresses itself in heterozygous condition is called Dominant allele.

Recessive allele - the allele which does not gets expressed in heterozygous condition is called recessive allele.plz mark it brainliest and follow me.

Answer 2

Dominant alleles: The genes which decides the trait in the presence of other different gene.In other words,the trait that is expressed is called dominant alleles and is denoted by capital letter.

Recessive Alleles: The gene which decides  the trait in the presence of other identical genes. In other words, the trait that is not expressed is called recessive alleles and is denoted by small letters.

The traits due to dominant alleles are always expressed even when a recessive allele is present.

Traits due to recessive alleles are only observed when two recessive alleles are present.

For example,

If an individual inherits:

☆ Two tall alleles (TT), the person will be tall.

☆One tall allele(T) and one short allele(t), then the person will be tall.

☆ Two short alleles(t t), that is recessive,then the person will be short.
