Document Summary

Xy = male: genetic diversity, genotype: an individual"s generic heritage, the actual genetic material, phenotype: the way an individual"s genotype is expressed in observed & measurable characteristics, dominate-recessive genes principle. Inbreeding: reproduction from the mating of 2 genetically related parents. Increases homozygosity (more similar genes) which can increase individual"s susceptibility to genetic disorders: decreases genetic diversity results in less fit offspring. Increases expression of recessive genes which may be detrimental. Reduced immune system functioning: x-linked inheritance, color blindness: inability or decreased ability to see color, or perceive color differences (can be total or partial, gene variations and genetic counseling, gene-linked variations due to harmful genes. Some gene-linked variations include cystic fibrosis, hemophilia, huntington disease, phenylketonuria, sickle-cell anemia, spina bifida, tay-sachs disease: dealing with genetic variations. Should parents have the right to intervene or alter a child"s genetic for a preferred trait? (e. g. eye colour)
