10
9 Took courses in this subject at the University of Vienna that later helped him with his genetic studies

53
52 What is dominant?
54
53 Separation of factors or alleles during the formation of gametes
55
54 What is the Law of Segregation?
56

59
58 Number of Possible allele Combinations in an F 1 Dihybrid Cross
60
59 What is four?
61
60 Used to represent alleles or factors that mask others
62
61 What is a Capital Letter?
63
62 States that recessive trait alleles have no effect on phenotype when paired with a dominant trait allele
64
63 What is the Law of Dominance?
65
64 Gives hybrids an appearance in between the phenotypes of the two parents
66
65 What is Incomplete Dominance?
67
66 Multiple alleles for human blood type is an example
68
