How are terms homozygous and heterozygous different

Answer 1

Homozygous and heterozygous are terms used to describe the genetic makeup of an organism with regards to a particular gene or trait.

Homozygous refers to an organism that has two identical alleles for a particular gene. For example, if an organism has two dominant alleles (AA) or two recessive alleles (aa) for a specific trait, it would be considered homozygous for that trait.

Heterozygous, on the other hand, refers to an organism that has two different alleles for a particular gene. For example, if an organism has one dominant allele and one recessive allele (Aa) for a specific trait, it would be considered heterozygous for that trait.

In summary, the main difference between homozygous and heterozygous is that homozygous organisms have two identical alleles for a gene, while heterozygous organisms have two different alleles for a gene.
