8) Early in the twentieth century, Walter Sutton and Theodore Boveri noted that the behavior of
chromosomes during meiosis is identical to the behavior of genes during gamete formation. They
proposed that genes are carried on chromosomes, which led to the basis of the . Accurate Answer:
Chromosome Theory of Inheritance
Section: 1.2
9) What is a mutation?
Accurate Answer: A mutation is an inherited change in a gene. Section: 1.2
10) What is a simple definition of an allele? Accurate Answer: An allele is a variant form of a gene.
Section: 1.2
11) Until the mid-1940s, many scientists considered proteins to be the likely candidates for the genetic
material. Why?
Accurate Answer: Proteins are the most abundant, universally distributed components in cells.
Because of their great structural and functional diversity, they were considered likely candidates.
Section: 1.2
12) Name the individual who, while working with the garden pea in the mid-1850s, demonstrated
quantitative patterns of heredity and developed a theory involving the behavior of hereditary
factors.
Accurate Answer: Gregor Mendel Section: 1.2
