CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -The combination of alleles that an organism carries constitutes its genotype. If the paired alleles are the same, the organism’s genotype is said to be homozygous for that trait; if they are different, the organism’s genotype is heterozygous.

Detailed explanation-2: -If an organism has two copies of the same allele, for example AA or aa, it is homozygous for that trait.

Detailed explanation-3: -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-4: -homozygote, an organism with identical pairs of genes (or alleles) for a specific trait. If both of the two gametes (sex cells) that fuse during fertilization carry the same form of the gene for a specific trait, the organism is said to be homozygous for that trait.
