Heterozygous in biology refers to an individual having two different alleles for a particular gene. This means that one allele is dominant over the other, resulting in a dominant phenotype. Heterozygous individuals display a combination of traits from both alleles.
The name of the gene pair that consists of a dominant and recessive allele, i.e. (Xx) will be a heterozygous allele. In this situation, the characteristics of the dominant characteristic will mask that of the recessive allele. People have have a heterozygous genotype may be carriers for diseases that reside on the recessive allele.
If it's not a heterozygous, the alleles would either be two capital letters (TT) or two lowercase letters (tt). This is because the organism has either both two dominant alleles or two recessive alleles.
Heterozygous alleles are used to describe the 'parents' when creating a test cross chart. When completing a test cross there is more than comparing alleles, you are really comparing genetics. Heterozygous YY or yy versus Homozygous Yy, is just the first to consider.
The organism is homozygous dominant for that trait.
Heterozygous induviduals pass the dominant and recessive alleles to offspring
a heterozygous individual has different alleles because one is dominant but the other is recessive.
Heterozygous means that it carries both dominant and recessive traits (as opposed to homozygous which carries only one) - the dominant trait is the one which is expressed (phenotype). A heterozygous trait can be expressed as Rr - "R" the dominant trait and "r" the recessive trait.
Organisms with alleles BB are considered homozygous dominant. This means that the dominant allele (B) is expressed in the phenotype. Dominant alleles mask the effects of recessive alleles in heterozygous individuals.
When an allele creates a visible trait, it is called a dominant allele. Dominant alleles mask the expression of recessive alleles when present in a heterozygous individual.
In a heterozygous genotype, an individual possesses two different alleles for a particular gene, with one being dominant and the other recessive. The dominant allele is expressed in the phenotype, while the recessive allele is not unless two recessive alleles are present.

2, it means that both of the alleles are different when compared to homozygous. Homozygous alleles are like aa or AA. Heterozygous simply means Aa so it has one dominant and one recessive allele
Homozygous dominant and heterozygous both are a dominant phenotype.
When the alleles are different the organism is heterozygous for that trait. Another way of putting it is to say the genotype is heterozygous for that trait. The dominant allele will be seen in the phenotype ie what is displayed.Most traits are governed by more than one pair of alleles.
"Heterozygous" and "homozygous" are terms that refer to alleles, which, in genetics determine what trait, from which parent, will appear in the offspring. Alleles can be either Dominant or Recessive. Every organism has two alleles, which can both be dominant, both recessive, or one of each.So,If an organism heterozygous, it has one recessive and one dominant allele.If an organism is homozygous then both of its alleles are the same; you need to specify if they are homozygous recessive (both alleles are recessive) or homozygous dominant (both alleles are dominant).
