21.   First, they say, it has become clear that mice have essentially the same genes as humans, but rearranged.

22.   His objective was to chart the extent of genetic variation among the same genes in different species.

23.   Humans have the same gene, Helfand said.

24.   If both parents carried the same recessive gene and they both passed it on to a child, that would produce a lethal disease.

25.   Identical twins share the same genes, while fraternal twins share half on average.

26.   Identical twins share the same genes.

27.   It is tempting, for instance, to eliminate the gene that causes sickle cell anemia, and then we are reminded that the same gene protects against malaria.

28.   It would be a clinical researcher, however, who would discover that the same gene mutation makes people vulnerable to colon cancer.

29.   Marrying a close relative risks having a child who inherits bad versions of the same gene, one from each parent.

30.   Plant breeders have unknowingly become adept at fiddling with these very same genes.
