An allele whose trait always shows up in the organism when the alllele is present

• Dominant Allele

• mutualism

• sybiosis

• species

An allele that is hidden whenever the dominant allele is present.

• Recessive Allele

• quantify

• tisssue

• trait

The flower color in pea plants exists in two versions--purple and white. What are these alternate versions of a gene are called?

• variant

• hybrids

• filials

• alleles

What is incomplete dominance?

• a blending of two traits (pink snap dragons)

• when one trait shows up and the other doesn't

• when both traits show up (speckled chickens)

What type of inheritance pattern do two alleles for a gene follow if their traits blend together on the offspring?

• Incomplete dominance

• Codominance

​ ​ (a)   have both alleles equally expressed, while ​ (b)   has an intermediate between the two parents, neither trait is dominant.

• codominant traits

• incomplete dominance

• dominant

• recessive

What does each chromosome in a living cell contain that contains all of the information an organism needs to express its parents' traits?

• DNA

• traits

• chromatids

• heterozygous alleles

What symbols are used to denote the homozygous genotype of the purple-flowered pea plant and the homozygous genotype of the white-flowered pea plant?

• AA and Aa

• Aa and pA

• Ap and Ap

• AA and aa

Which tool can help you predict the likelihood of getting all purple or all white plants in the F1 generation after crossing a homozygous purple plant and a homozygous white plant?

• a venn diagram

• a punnett square

• genetic engineering
