Explanation:
Detailed explanation-1: -The notation tt means the homozygous condition, wherein the homologous pair contains same alleles of a gene.
Detailed explanation-2: -An organism can be either homozygous dominant ( TT ) or homozygous recessive ( tt ). If an organism has two different alleles ( Tt ) for a certain gene, it is known as heterozygous (hetero-means different).
Detailed explanation-3: -“The cross between two monohybrid traits (TT and tt) is called a Monohybrid Cross.” Monohybrid cross is responsible for the inheritance of one gene. It can be easily shown through a Punnett Square.
Detailed explanation-4: -When a heterozygous plant is self crossed with itself in a monohybrid cross, the genotypic ratio obtained is TT:Tt:tt = 1:2:1.
