How are alleles of particular gene differ from each other ? Explain its significance.
Alleles of a particular gene differ from each other on the basis of certain changes (i.e., mutations) in the genetic material (segment of $DNA$ or $RNA$). Different alleles of a gene increases the variability or variation among the organisms. These variations are necessary for evolution and adaptations.
In a dihybrid cross $80$ plants are obtained. The ratio of homozygous and heterozygous shall be
In Mendel experiment he crossed tall and dwarf pea plant to study inheritance of one.....
The genotypic ratio of a monohybrid cross in $F_{2}$-generation is
The crossing of a homozygous tall plant with a dwarf in $F2$ would yield plants in the ratio of
''Genes contain the information that is required to express a particular trait.'' Explain.
