Question

What is illustrated in Figure 14–7?


A. mutation

B. dominance

C. electrophoresis

D. nondisjunction

Answer 1

A mutation is a change to the actual genetic code that makes up a chromosome, as in the bases change to bases they shouldn't be.

Dominance describes the relationship between two genes.

Electrophoresis is a lab experiment - when a molecule like a protein or a piece of DNA is pulled through basically a mesh. Small molecules travelling through the holes in the mesh faster than big molecules. It's like a molecular sieve.

And nondisjunction is when chromosomes fail to separate properly during meiosis.
