A breed of chicken shows codominance for feather color. One allele codes for black feathers, another codes for white feathers. The feathers of heterozygous chickens of this breed will be:

• all black
• all white
• all gray
• speckled black and white

This type of inheritance pattern shows BOTH traits in possible offspring

• complete dominance
• incomplete dominance
• co-dominance
• dominant pattern

A roan cow shows co-dominance in fur color (orange and white). What is the phenotype ratio expected if a roan cow and a roan steer mate together?

• 4: Orange and White
• 1: Orange : 1 White
• 2 Orange: 2 Orange and White: 0 White
• 1: Orange: 2 Orange and White: 1 White

In Andalusian fowls, black individuals (BB) and white individuals (bb) are homozygous. Heterozygous individuals are grey (Bb).  
What is the genotype ratio for a cross between a grey fowl and a white fowl?

• 2 BB: 2 Bb: 0 bb
• 0 BB: 4 Bb: 0 bb
• 0 BB: 2 Bb: 2 b
• 1 BB: 2 Bb: 1 bb

In some carnations, flower color exhibits codominance. When crosses, Red (R) and white (W) flowers make speckled flowers (RW) that show both colors.
Complete a cross between 2 speckled flowers and find the genotype ratio.

• 0 RR: 4 RW: 0 WW
• 2 RR: 2 RW: 0 WW
• 1 RR: 2 RW: 1 WW
• 0 RR: 2 RW: 2 WW

What type of inheritance pattern is shown here?

• Complete Dominance
• Incomplete Dominance
• Co-Dominance
• Sex-linked

AB blood type is an example of what type of inheritance?

• complete dominance
• incomplete dominance
• codominance
• polygenic inheritance

A red flowered plant (RR) breeds 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%
