Textbook Question
Chapter 27, Problem 5CONQ
The term polymorphism can refer to both genes and traits. Explain what is meant by a polymorphic gene and a polymorphic trait. If a gene is polymorphic, does the trait that the gene affects also have to be polymorphic? Explain why or why not.

IN TRANSYLVANIA, SOME PEOPLE EXHIBIT TWO UNUSUAL TRAITS IN WHICH THEY HAVE VERY LONG FRONT TEETH AND THE INABILITY TO BE AWAKE WHEN THE SUN IS UP. BOTH OF THESE TRAITS APPEAR TO BE RECESSIVE. IF A WOMAN WHO IS HETEROZYGOUS FOR TEETH AND HOMOZYGOUS NORMAL FOR BEING IN THE SUN MARRIES A MAN WHO HAS BOTH THESE TRAITS, WHAT COULD BE THE PHENOTYPES AND GENOTYPES OF THEIR CHILDREN? USE A PUNNET SQUARE AND SHOW ALL WORK. LIST THE RATIOS FOR THE GENOTYPES AND PHENOTYPES.
Which term indicates that a single gene has two or more alleles present in a population? A. Point mutation B. Genotype C. Polymorphism D. Pleiotropy
How similar are the genes of different species? Does this reflect how different or similar the traits seem to be?
