Differentiate between the following – (a) Dominance and Recessive
Explanation Dominance means the ability of an allele to express itself in presence or absence of the recessive allele. Dominant allele does not require similar allele to express its effect on phenotype. Example: Tt will always be tall, if T is a dominant allele. Recessive means the inability of an allele to express itself in presence of dominant allele. Recessive allele do require a similar allele to express its effect on phenotype. Example: tt is small. Final answer Dominant allele are able to express itself in the presence of recessive allele. Example: TT and Tt results into tall plant (dominant allele) while tt results into small plant(recessive allele).
