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.
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.
Solar energy is the original source of energy in most ecosystems. There must be a continual supply, due to energy only flowing in one direction in an ecosystem. Energy that is lost to heat must be replaced by more energy.
