Co-Dominance Versus Incomplete Dominance In Flower Color

The video from Somos Biology explains the differences between co-dominance and incomplete dominance. It uses visual examples of flowers to illustrate how co-dominance results in both parental phenotypes being visible, while incomplete dominance results in a blend of phenotypes. The video also discusses the effects of alleles and provides examples such as the Roan character of cows and the inheritance of AB blood group for co-dominance, and traits like height and eye color for incomplete dominance. The video concludes with a call to action for viewers to engage with the content.

What is the main topic discussed in the video?

• The process of photosynthesis

• The structure of DNA

• The difference between co-dominance and incomplete dominance

• The lifecycle of plants

In the context of flower color, what does incomplete dominance result in?

• A flower with both red and white spots

• A completely red flower

• A pink flower

• A completely white flower

How is co-dominance visually represented in flowers?

• A blend of colors

• A single color

• Both parental colors visible

• A new color not seen in parents

What is a key characteristic of alleles in co-dominance?

• They are not expressed at all

• They show their effects independently

• They do not show any effect

• They blend to form a new trait

What is the result of incomplete dominance in terms of phenotype?

• A phenotype that is a blend of both parents

• A phenotype identical to one parent

• A phenotype that is not expressed

• A phenotype that is completely new

In incomplete dominance, how do alleles express themselves?

• As a blend

• Independently

• As a dominant trait

• Not at all

Which of the following is an example of co-dominance?

• Skin color

• Roan character of cows

• Inheritance of height

• Eye color

Which blood group is an example of co-dominance?

• B blood group

• A blood group

• O blood group

• AB blood group

Which of the following is NOT an example of incomplete dominance?

• Eye color

• Height

• Weight

• AB blood group

What is the result when both A and B alleles are present in blood type?

• A blood type

• O blood type

• B blood type

• AB blood type
