Genomic Structure and Evolution of Multigene Families: “Flowers” on the Human Genome

Table 3

Comparison of gene density of Flowers with randomly selected regions. Except Flowers with 𝐷 length ≥ 1 Mb, the number of Flower genes was compared to that of 1,000 randomly selected regions on the human genome.

		Gene number in 277 Flowers	Gene number/10 Kb	Protein-coding gene number	Protein-coding gene number/10 kb
Flower		1,841	0.61*	1,030	0.34*
Randomly selected region (𝑛=1,000)	Mean	371	0.12	282	0.09
	S.D.	39	0.01	30	0.01
	Min.	272	0.09	204	0.07
	Max.	561	0.19	439	0.15
