HomozygosisenUKHomozygosisthe state of the genetic apparatus of an organism in which homologous chromosomes have the identical form of a given gene. The transition of a gene into the homozygous state leads to the manifestation in the organism’s structure and function (phenotype) of recessive alleles, whose effect in heterozygosis is suppressed by the dominant alleles. A test for homozygosis is the absence of splitting in certain forms of crossbreeding. A homozygous organism produces only one form of gamete for a given gene. homozygosisenUKhomozygosis[ho″mo-zi-go´sis]ho·mo·zy·gos·i·ty, homozygosis (hō'mō-zī-gos'i-tē, -zī-gō'sis),homozygosis(hō′mō-zī-gō′sĭs, -mə-, hŏm′ə-)ho·mo·zy·gos·i·ty, homozygosis (hō'mō-zī-gos'i-tē, -zī-gō'sis) |
