The scientist claims that genetic variation has occurred in the process. Is the scientist correct? Why or why not?
a
The scientist is incorrect. The process shown in the diagram is a deletion mutation, in which one nucleotide sequence joins another, causing genetic information to be maintained.
b
The scientist is incorrect. The process shown in the diagram is nondisjunction, in which a mutated chromosome does not duplicate normally, causing genetic information to be maintained.
c
The scientist is correct. The process shown in the diagram is nondisjunction, in which chromosomes fail to separate normally, causing an incorrect amount of genetic information to be inherited.
d
The scientist is correct. The process shown in the diagram is a deletion mutation, in which a nucleotide sequence has been omitted, causing an incorrect amount of genetic information to be inherited.
d
The scientist is correct. The process shown in the diagram is a deletion mutation, in which a nucleotide sequence has been omitted, causing an incorrect amount of genetic information to be inherited.
