What is Homozygous?
The term “homozygous” comes from two words, “homo,” meaning “same,” and “zygous,” which refers to having zygotes of a particular kind. When both alleles for a gene are identical, an individual is considered homozygous for that gene. For instance, you may have two identical or very similar alleles for a specific gene that determines characteristics like hazel brown eyes.
The traits expressed by homozygous individuals are decided by the alleles within their genetic makeup. For example, when someone is homozygous dominant, the dominant trait will be evident, while homozygous recessive individuals will display the recessive trait. Homozygous breeding contributes to preserving the purity of particular traits across successive generations.
Difference Between Homozygous And Heterozygous
Homozygous and heterozygous are terms used in genetics to describe the types of alleles an individual possesses for a particular gene. A homozygous individual carries two identical alleles(RR or rr) for a specific gene while a heterozygous individual carries two different alleles(Rr) for a specific gene. The concepts of homozygous and heterozygous genotypes are fundamental in explaining the inheritance patterns of traits as described by Gregor Mendel.
