A heterozygous genotype, is the genetic makeup of different alleles.

Heterozygous
There are many genotypes with specific names depending on the organism. For example, in humans, genotypes can include AA, Aa, or aa for single gene traits. In plants, genotypes may be represented by combinations of letters and symbols. Overall, genotypes are named based on the specific alleles an individual carries for a particular gene.
The possible genotypes of the gametes in a genetic cross involving the keyword "genotypes" are determined by the specific alleles present in the parents. These genotypes can be represented by different combinations of alleles, such as homozygous dominant (AA), homozygous recessive (aa), or heterozygous (Aa).
heterozygous genotypes are two different traits which one is reccessive and one is dominant. to be homozygous means that both the traits are either both reccessive or both dominant
Three types of genotypes that exist for pea plant height are: TT - Homozygous dominant genotype for tall height Tt - Heterozygous genotype for tall height tt - Homozygous recessive genotype for short height
Generally, if the parents are heterozygous and one allele is dominant over the other there are only 2 phenotypes and 3 genotypes. Parents Aa can produce AA, Aa and aa offspring. If the heterozygous individuals have an intermediate phenotype, then three genotypes and 3 phenotypes are possible. If 2 traits are being studied using heterozygous parents AaBb then the possible Genotypes are AABB, AABb, AAbb, AaBB, AaBb, Aabb, aaBb, aaBB, aabb which is nine genotypes. But there are 4 phenotypes. AABB AABb AaBB AaBb are phenotypically the same. aaBb, aaBB are phenotypically the same. Aabb, AAbb are phenotypically the same. aabb
He used the term hybrid.
Blood type A may be AA homozygous or AO heterozygous. This blood type has at least one "A" and no "B."
In a dihybrid cross, the expected genotypic ratio is 1:2:1 for homozygous dominant: heterozygous: homozygous recessive genotypes, respectively. In a monohybrid cross, the expected genotypic ratio is 1:2:1 for homozygous dominant: heterozygous: homozygous recessive genotypes, respectively.
The man could have either free hanging or attached earlobes. His possible genotypes could be either homozygous for free hanging earlobes (LL) or heterozygous for free hanging and attached earlobes (Ll).
