Notes punnett squares

1. 1. Notes: Punnett squares (pg 8)
2. 2. Notes: Punnett squares (pg 8)• Punnett square = Diagram used to predict the possible offspring of a cross
3. 3. Notes: Punnett squares (pg 8)• Punnett square = Diagram used to predict the possible offspring of a cross• Created by Reginald Punnett
4. 4. Notes: Punnett squares (pg 8)• Punnett square = Diagram used to predict the possible offspring of a cross• Created by Reginald Punnett• The alleles of one parent are written across the top of the square (one allele per box) and those of the other parent are written on the side
5. 5. • Genotype frequency: 25% BB, 50% Bb, 25% bb
6. 6. • Genotype frequency: 25% BB, 50% Bb, 25% bb• Phenotype frequency: 75% Black, 25% White
7. 7. Output (pg 9)• Guinea pig diagram• Tape as close to the top as you can
8. 8. Example Problem (pg 8)• In guinea pigs, black fur (B) is dominant to white fur (b). A heterozygous black female mates with a white male. What are the genotype and phenotype ratios of the offspring?
9. 9. Output (pg 9)• Make up a problem that requires a Punnett square to solve it. Write it on pg 9. Then trade interactive notes with your neighbor and have them try to solve it
