104. What is genetic recombination?
105. Genetic recombination is opposite to linked genes, which always produce the same
phenotype. What is the mechanism behind genetic recombination?
106. Define parental phenotypes and non parental phenotypes.
107. Occurrence of what with a frequency of over 50% indicates linked genes?
108. What process during cell division allows for genetic recombination?
109. What is involved in small scale changes to phenotype?
110. Give examples of large scale chromosomal changes.
111. What is polyploidy? Triploidy? Tetraploidy? Aneuploidy?
112. How can triploidy, tetraploidy and aneuploidy result?
113. What does it mean that polyploidy is more common than aneuploidy?
114. Nondisjunction is related to abnormal chromosome number. Define the word. What is
the result of nondisjunction?
115. What is the amount of chromosomes in both daughter cells if nondisjunction
occurred in meiosis I? Meiosis II?
116. Define monosomic and trisomic.
117. Define deletion, duplication, inversion and translocation in chromosomes.
118. 2 of which are especially likely during which part of meiosis?
119. 2 of which can alter phenotype? How do they do so?
120. Which of the 4 is most dangerous? Why?
DNA and its Molecular Basis of Inheritance
121. Nucleic acids are unique in their ability to do what?
122. How do bacteriophages relate to how we found out nucleic acids were what DNA
was made of?
123. What are Erwin Chargaff rules?
124. What do cytosine, thymine and uracil have in common besides being bases?
Adenine and Guanine?
125. What are in all the carbon positions for both sugars?
a.
126. What does x-ray crystallography do? What was its role in building the structural
model of DNA? Who used the technique? Who created the model?
