Explanation

Heterozygous. The diploid condition in which the alleles at a given locus are identical is called homozygous or pulls. In homozygous condition, organism have two similar genes or alleles for a particular character in homologous pair of chromosomes, e.g., TT or tt. Organisms containing two different alleles or individual containing both dominant and recessive genes of an allele pair, e.g., Tt is known as heterozygous or hybrid
