Which one of these shows an affected male (one that shows the phenotype we are focused on)?

• 
• 
•

• Impossible to tell

Which of the following genotypes are homozygous? (can select multiple if necessary)

• Rr

• rr

Is this a dominant or recessive trait?

• Definitely dominant

• Definitely recessive

Dogs with pink and black gums, or black and white spotted cows are both examples of:

• Recessive traits

• Codominance

• Incomplete Dominance

• Dominant traits

If a rabbit with genotype RR has short fur, rr has long fur, and Rr has medium-length fur, this is an example of:
