CHROMOSOMES AND MOLECULAR HOMOLOGY -
- The DNA content of diploid cells is similar.
- Hoyer et al in 1965 showed that DNA of humans was 100% similar with chimpanzee and 94% with gibbon.
- Apes possess 48 chromosomes where as humans possess 46 chromosomes.
- Bacillary patterns of many chromosomes are same in humans and apes.
- AB blood groups is found both in apes and man.
- Luckerhandl in 1963 proposed that hemoglobins of human and gorilla differ in only one amino acid is each of the two types of polypeptides.
- Groundman is 1962 proposed that protein homology is maximum between human and chimpanzee, followed by human and gorilla.
