täysisisaruksia
Täysisisaruksia refers to full siblings in Finnish. This term denotes individuals who share both biological parents. Unlike half-siblings, who share only one parent, full siblings have identical genetic material inherited from their mother and father. This shared parentage often leads to a higher degree of genetic similarity and can influence shared physical traits, predispositions to certain conditions, and familial resemblances. The concept of täysisisaruksia is significant in understanding family structures, inheritance, and genetic studies. It distinguishes them from other sibling relationships such as half-siblings (puolisisaruksia) or step-siblings (sisarpuolia), who have different genetic or familial connections. The term emphasizes the complete, shared biological lineage between the individuals.
