Punnett Squares Practice

In a punnet square where are the parent alleles written?

• Top and inside the boxes
• Only on the left and right side of the boxes. 
• outside of the boxes (top and left side)
• All on the top side of the boxes

Each one of the boxes on the Punnett Square represents what probability of an offsprings' genotype?

• 25%
• 1%
• 10%
• 0%
