Question 13

Traits that mask the presence of other traits

Answer 13

Dominant Traits

Question 14

Traits that are being masked by the presence of other traits

Answer 14

Recessive Traits

Question 15

Mendel’s law of dominance states that: “When parents with pure, contrasting traits are crossed together, only one form of trait appears in the next generation. The hybrid offsprings will exhibit only the dominant trait in the phenotype.” Law of dominance is known as the first law of inheritance

Answer 15

Mendel’s law of dominance states that: “When parents with pure, contrasting traits are crossed together, only one form of trait appears in the next generation. The hybrid offsprings will exhibit only the dominant trait in the phenotype.” Law of dominance is known as the first law of inheritance

Question 16

No allele is dominant, they interact to produce a new phenotype

Answer 16

Incomplete Dominance
