Traits Are Sometimes Said to "Skip a Generation

question 40

Multiple Choice

Traits are sometimes said to "skip a generation." How does this happen according to Mendel's experiments?

• A) If an allele determining a trait is dominant, recessive alleles from either parent can mask it, like when Mendel's first generation of flowers from a white and purple parent where all purple.
• B) If an allele determining a trait is recessive, dominant alleles from either parent can mask it, like when Mendel's first generation of flowers from a white and purple parent were all purple.
• C) If an allele determining a trait is recessive, it sometimes just doesn't show up, regardless of what traits the parents have, like when Mendel only got purple flowers in the first generation.
• D) Sometimes mutations allow a new trait to mask a recessive trait for one generation. Mendel found this to be the case in his second generation where he got both purple and white flowers.
• E) Sometimes a recessive allele is only advantageous after several generations and so doesn't show up until then. Mendel saw this in the white flowers being produced by a cross between purple and white parents.
