25. How to complete Punnett Square
Determine which alleles are dominant or recessive
Make a key
In cats black coat is dominant over brown coat. Cross a heterozygous black cat with a brown cat. What is the probability that their offspring will have black coats?
BB= Black
Bb= Black
bb= brown

26. 3. Determine which alleles to use 4. Set up and work punnett square
5. Read results
Cross a heterozygous black cat with a brown cat. What is the probability that their offspring will have black coats?

27. Eye Color Brown eyes are (B) dominant over blue eyes (b)
Gina and Mark are heterozygous for brown eyes (Bb). What is the probability they will have children with brown eyes?

28. Pod Color
Green pods (G) are dominant over white pods (g) Cross two white pods What is the probability they will produce green offspring?

29. Freckles Not having freckles (F) is dominant over freckles (f)
Marie is heterozygous for not having freckles and Luis has freckles.
What is the probability they will have children with freckles?
What is the probability they will have children without freckles?

30. Coat Color
Black (B) is dominant over white (b) A homozygous dominant black cat is crossed with a white cat. What is the probability they will have white offspring?

31. Genetics and Blood Typing
What are the four blood types? A B AB O
What determines your blood type?
Genetics (parents)

32. Genetics and Blood Typing
Blood Type
(Phenotype)
Alleles
(Genotype) A AA AO B BB BO AB O OO

33. Example #1
Matt has type AB blood. Lucy is heterozygous for type B blood. What is the probability they will have children with type B blood?

34. Example #2
Mila is heterozygous for B blood. Ashton is homozygous for type A blood. What is the probability they will have children with type A blood?

35. Example #3
Marge is heterozygous for type B blood. Homer has type A blood. Bart has type O blood. Is this possible? Why or why not?

36. Incomplete Dominance allele
Neither _______ is _________ over the other
Results in a ________________
