AP Bio Heredity Unit Review-PART 1

Morgan crossed a pure-breeding wild type red-eyed fly with a mutant white eyed fly, producing an F₁ generation of all red eyed flies.  When he crossed his red-eyed flies with each other, the F₂ generation included both red- and white-eyed flies. However, all the white-eyed flies were male. What explains this result?   

• The gene involved was on the X chromosome.
• The gene involved was on the Y chromosome.
• The result is due to multifactorial inheritance.
• Other male-specific factors (such as hormones) influence eye color in flies.

The closer two genes are on a chromosome, the higher the probability that a crossover will occur between them.

• True
• False

What is transformation (with regard to bacteria)?

• The bacteria mutates

• A plasmid from one bacterium becomes incorporated into another

• The bacterium puts on it's cape and becomes a superhero

• The bacterium recieves enzymes from another bacterium.

Genetic variation can increase as a result of which of the following processes (select all that apply)

• Crossing over

• Conjugation

• Fertilization

• Binary fission
