A red flowered plant (RR) is crossed with a white flowered plant (WW). The gene for petal color in these plants expresses incomplete dominance.  What percentage of the offspring will have pink (RW) flowers?

• 0%
• 25%
• 50%
• 100%

What type of inheritance do two alleles have if their traits blend together? 

• Incomplete Dominance
• Co-Dominance

This type of inheritance pattern is a MIXTURE of both traits.

• incomplete dominance
• co-dominance
• complete dominance

Codominance occurs in calico cats, which allows for the Black and Tan colors to show. What percentage of the offspring will be calico (black and tan spotted)?

• 25

• 50

• 75

• 100

A brown rooster and a white chicken produced this speckled offspring:

• Incomplete dominance

• Codominance

• Complete dominance

Three or more alternative forms of a gene that can occupy the same locus.

• multiple alleles

• codominant

• polygenic

• incomplete dominance

What you see, or the physical appearance.

• Genotype
• Phenotype
• Homozygous
• Heterozygous

The different forms of a gene are called

• traits

• pollinators

• alleles

• hybrids

A section on a chromosome that has genetic information for one trait.

• trait
• gene
• chromosome

What type of inheritance is determined by multiple genes located at different loci on different chromosomes and there can be a range of traits?

• Codominance
• Incomplete dominance
• Polygenic traits
