Document Summary
Issues with gene studies numerical and biological perspective. Studying human genetics can be difficult from an ethical, research subjects. Good scientific studies require a large number of identical use as research subjects. Cannot (ethically or legally) clone identical human beings for biological and environmental factors (diet, lifestyle) Even large scale studies (e. g. , drug trials) are influenced by. Clones do exist, in the form of twins. Dizygotic (dz) twins result from two sperm fertilizing two eggs ( no more genetically similar than any other pair of full siblings ) Monozygotic (mz) twins result from single sperm fertilizing single egg, which then cleaves and becomes 2 separate zygotes ( two genetically identical babies ) Mz and dz and twins cont. single egg ( two genetically identical babies) Mz (monozygotic) twins result from single sperm fertilizing. The search for concordance particular trait, behaviour or characteristic (bartol, 1999) Concordance = the degree to which related pairs exhibit a.
