Front

Two snapdragon plants are crossed. One plant produces red flowers and the other plant produces white flowers. The cross between these two plants produces snapdragon plants with pink flowers. Which statement explains why the offspring have pink flowers?

Back

The offspring have one allele that codes for red and one allele that codes for white.

Front

What is a genotype?

Back

The genetic makeup of an organism, represented by alleles.

Front

What is a phenotype?

Back

The observable characteristics or traits of an organism.

Front

What does it mean for an allele to be dominant?

Back

It is the allele that expresses its trait even in the presence of a recessive allele.

Front

What does it mean for an allele to be recessive?

Back

It is the allele that only expresses its trait when two copies are present.

Front

What is a Punnett square used for?

Back

To predict the genetic outcomes of a cross between two organisms.
