A snapdragon produces either yellow or white flowers. The dominant allele (Y) produces yellow flower color and the recessive allele (y) produces white color. Which color would you expect to be more common and why? Mark all that apply (2)

• White. The allele for white is recessive and recessive traits always show.

• Yellow. The allele for yellow is dominant and dominant traits almost always show.

• YY or Yy

• yy

Why does sexual reproduction lead to variation of traits in a population? Mark all that apply. (3)

• Organisms only receive genetic information from one parent, which doesn't lead to trait variation.

• Over generations, the variation of traits in a population changes depending upon the traits of the individuals that reproduce.

• All organisms are the same.

• Genetic information is a combination of alleles (or genes), which code for traits.

• Organisms receive genetic information from both parents, which leads to trait variation in individuals.
