Detailed explanation-1: -An organism with two identical alleles is homozygous.
Detailed explanation-2: -Homozygous means having identical alleles for the same trait. i.e having 2 copies of the dominant allele or 2 copies of the recessive allele. Example: TT for tallness and tt for dwarfs. TT is homozygous for dominant character/trait and tt is homozygous for recessive character/trait.
Detailed explanation-3: -organism. 12. Homozygous: Having two identical alleles for a trait.
Detailed explanation-4: -Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ.
Detailed explanation-5: -Dominant and recessive alleles can be used to explain Mendel’s observations. An organism that has two identical (same) alleles for a trait is called a purebred. purebred in the U.S. two recessive (tt).
