The Greek ideal of the hero most closely resembles today’s freeagent superstar.

#General Aptitude
  1. A superstar is an athlete who commands a great salary based on his individual skills.
  2. The Greek warrior’s focus was on grasping at immortality, and he did this by ensuring that his name would live on, long after he died.
  3. The Greek hero valued self-interest above loyalty to a cause, his king, or to his army, just as the free-agent superstar values his contract salary above any special team, coach, or the game.
  4. The Greek hero was impressive in his performance on the battlefield as well as in the sports arena.

#Unit 8. Inheritance Biology

Genes that control coat color in mammals represent some of the best early examples of genes with multiple alleles exhibiting different phenotypes. A classic example is the C gene in hamsters. Three of the known alleles of this gene are C, ca and ck. Each supplies a different amount of black pigment to the coat hair. The phenotypes of three different homozygous strains are as follows.
Based on the concepts of recessivity, determine whether ck and ca were dominant or recessive alleles by crossing the true-breeding albino hamsters  with the true-breeding sepia hamsters. From the resulting F1 progeny phenotype, what would be the ratio of F2 phenotype

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?

In a rare blood type referred to as the Bombay phenotype, individuals are unable to attach the A or B antigens to their red blood cells. Individuals that are homozygous recessive for gene "H" have the Bombay phenotype and their blood type is type "O" regardless of their ABO genotype. This is an example of what extension of Mendelian inheritance?
