Question

an allele whose trait always shows up in the organism when the allele is present is called a

genetic anomaly

recessive allele

monster allele

dominant allele

Explanation:

To solve this, we recall the definitions of genetic terms:

• A "genetic anomaly" refers to an abnormal genetic condition, not related to allele expression.
• A "recessive allele" is only expressed when two copies are present (homozygous recessive).
• "Monster allele" is not a valid genetic term.
• A "dominant allele" is defined as an allele whose trait is always expressed in the organism when the allele is present (even in heterozygous condition, where only one copy is present).

Answer:

dominant allele (the option with "dominant allele" text, likely the red - colored option in the given choices)
