• Ratio two numbers that show the relationship
  between two amounts
• Written as number number 54
• Percentage a ratio that compares a number to
  100. ex 50 100 50
• Probability percentage/chance that something
  will happen.
• The probability of having an offspring with brown
  hair is 75 or there is a 75 chance

• Steps to making a Punnett Square

10
How to complete a Punnett Square

• Step 1 draw the 4 square
• Step 2 put parent alleles on the outside of
  Punnett square.
• dad top
• mom left side

Male / Father alleles B b
Female / Mom Alleles b b
11
Male / Father alleles B b

• Step 3. Distribute parent alleles
• Bring dad alleles down
• Bring mom alleles across
• Step 4. Determine ratio and probability/percentage
  
• - Look at genotypes inside
• Bb 2 bb 2
• Ratio 22
• 50 chance of brown eyes
• 50 chance of blue eyes
