A mutation that causes a change in the number of chromosomes.
Nondisjunction
The _________________ is the genetic makeup of an organism.
Genotype
A phenotype that is the intermediate between two traits is showing what kind of
dominance?
Incomplete Dominance
An overexpression of one allele causes the offspring to die. This is an example of
what kind of gene?
