Mutations & Punnett Squares Practice

The environment in which plants are grown affects their appearance.

Recessive traits are more likely to be expressed than dominant traits.

The appearance of certain traits is predictable and is controlled by genes.

Crossing pea plants in the wild produces results without observable patterns.

DNA could be removed from the genomes of the crop plants.

DNA from plants that are adapted to dry areas could be added to the genomes of the crop plants.

DNA from a variety of nonagricultural plants could be added to the genomes of the crop plants

DNA from dry weather crops could be added to the fertilizer used on the crop plants.

The sheep are commonly bred for food and wool production.

The thickness of the wool is only medium and cannot be used for light clothing.

Larger muscles give rise to leaner meat for consumers.

Larger offspring causes more difficult births.

Dominant alleles are always expressed and recessive alleles are never expressed.

Recessive alleles are always expressed and dominant alleles are never expressed.

Dominant alleles are only expressed when they're paired with other dominant alleles.

Recessive alleles are only expressed when they're paired with other recessive alleles.
