Use the data in the accompanying table to answer the question. Minutes Spent in Cell Cycle Phases-

Cell type	G1	S	G2	M
Beta	18	24	12	16
Delta	100	1	0	0
Gamma	18	48	14	20

The data in the table were obtained from a study of the length of time spent in each phase of the cell cycle by cells of three eukaryotic organisms designated beta, delta, and gamma. What is the best explanation for the data associated with delta cells?

#Unit 8. Inheritance Biology

The recessive mutant allele that causes cystic fibrosis is much more frequent in Caucasians population than in other world populations. Some scientists believe heterozygotes must have had a survival advantage during plagues such as cholera that occasionally swept through this population. What concept does this illustrate?
