1. Somatic cell: A somatic cell is any biological cell forming the body of a multicellular organism other than a gamete, germ cell, or undifferentiated stem cell. These cells are diploid, meaning they contain two complete sets of chromosomes, one inherited from each parent. 2. Recessive: In genetics, a recessive trait is one that is expressed only when two copies of the same allele are present. If an individual has one dominant allele and one recessive allele, the dominant trait will be expressed. 3. Recessive Allele: A recessive allele is a variant of a gene that is only expressed phenotypically when two copies of it are present in an individual. It is masked by the presence of a dominant allele. Got more terminology for me? 📸
