homozygoottisena

Homozygoottisena, which translates to "homozygous" in English, describes a genetic state where an individual possesses two identical alleles for a particular gene. Alleles are different versions of the same gene. For instance, if a gene determines eye color and has an allele for blue eyes (B) and an allele for brown eyes (b), an individual who is homozygous for the blue eye trait would have two 'B' alleles (BB). Conversely, an individual homozygous for the brown eye trait would have two 'b' alleles (bb).

This state contrasts with being heterozygous, where an individual has two different alleles for a gene, such as Bb for eye color. In homozygous individuals, the trait expressed will be determined by the single type of allele present. If the allele is dominant, its corresponding trait will be expressed. If the allele is recessive, its corresponding trait will also be expressed because there is no dominant allele to mask it. The concept of homozygosity is fundamental to understanding inheritance patterns and genetic variation within populations. It plays a crucial role in determining observable characteristics, or phenotypes, in organisms.
