The word "heterozygous" simply means that your biological mother and your biological father, when they contributed their copies of a particular gene to you, they did so in a way so that the DNA sequence is slightly different.

What are examples of heterozygous?

Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous.

What is the meaning of homozygous and heterozygous?

Heterozygous is when different forms of a specific gene are inherited from each parent. Homozygous is when a gene inherited from each parent is identical. Basically, heterozygous means different while homozygous means the same.
