1 distribution of IBC's by size. Sizes range from 3 to 19 , 
2 with an average size of just over 10 . Committee sizes 
3 also varied by type of institution. Universities tended 
4 to have somewhat laryer panels than non-educat ional 
5 institutions did. 
6 Biographical data indicated that the committees 
7 were made up overwhelmingly of men. Also, most committee 
8 members, over 90 percent, were directly affiliated, in one 
9 way or another, with the university or research institution. 
10 The representation of different types of members 
H on IBC's is shown in Figure 2 . The pie-shaped figure 
12 indicates the membership composition of a typical IBC — 
13 a typical committee, the average number of members per 
1 4 committee in each of the nine membership categories. Not 
1 5 surprisingly, scientists in recombinant DNA disciplines 
10 represented the largest membership block. The representa- 
17 tion of recombinant DNA-related nembers is broader still, 
13 averaging close to 85 percent if you include peripherally 
19 related scientists and administrators. 
20 The proportions of public members, workers, 
21 non-related administrators and students each averaged 
22 less than two percent. Likewise, the representation of 
23 non-related disciplines was small. On the average, only 
24 nine percent of the committee members were scholars in 
25 disciplines unrelated to recombinant DNA.
