Table 2.

Characteristics of modified sequences generated according to the sequential ("ancestor-descendant") and diverging ("descendant1-descendant2") schemes.

PAM	"Ancestor-descendant"		"Descendant1-descendant2"
	%Id	%Indel	%id	PAM (id)	%indel	PAM (indel)
30	74.9%	3.3%	57.9%	60.55	6.6%	68.56
60	57.9%	5.4%	37.6%	122.25	10.7%	202.14
120	37.6%	7.5%	20.1%	245.08	14.7%	>830
240	20.2%	8.9%	10.5%	473.87	17.3%	> 830

Lines correspond to different values of PAM. The figures in columns are described in the text (subsection 2.2). All data are given as selected from 1000 sequence pairs. For control, the same data were obtained for a variety of 10,000 pairs; the results do not differ from those given in the table with an accuracy of tenths of a percent.
