Answer:
Alleles are the variant or alternative form of gene present on the homologous chromosome at a specific position, its function is to determine the genetic traits.
Step-by-step explanation:
Alleles are an alternative form of the gene, and they are present on the homologous chromosome.
- If the function of the allele is to code for a specific type of protein and to determine the genetic traits.
- If the Alleles are the same they are called homozygous.
- If the alleles are different they are called heterozygous.
- If the allele is dominated it denoted by a capital letter, whereas recessive allele by small letters.
- Example : flower color in the pea plants,dominant allele is purple and recessive one white allele.
