Question

What are some examples of alleles?

Answer 1

Alleles:

1. Alternative forms of genes are called alleles.
2. The two alleles of a gene occupy corresponding positions on homologous chromosomes and control the same character (for example, the height of a plant) but produce different effects (short or tall).
3. A dominant allele hides a recessive allele's expression. An uppercase letter is used to signify it.
4. A recessive allele exerts its effect only in the homozygous state. It is represented by a lower case letter.

Some examples of alleles:

1. The dominant purple and recessive white alleles are responsible for flower color in pea plants.
2. Black, blue, green, and brown eye color alleles.
3. Black, brown, blonde hair color alleles.
