Understanding Co-Dominance in Genetics

The video tutorial explains co-dominance, a genetic concept where both traits are equally dominant and visible in the phenotype. It contrasts this with incomplete dominance, where traits blend to form a new characteristic. The prefix 'co' signifies togetherness, as seen in words like coexist and cooperate. An example of co-dominance is given with cows, where offspring show both black and white traits distinctly, unlike incomplete dominance, which results in a blend of traits.

What does the prefix 'co' in co-dominance suggest?

• Separation

• Togetherness

• Dominance

• Difference

In co-dominance, how are the traits expressed in the phenotype?

• Both traits are equally visible

• One trait is dominant over the other

• Neither trait is visible

• Traits are blended together

In the context of genetics, what does co-dominance mean?

• One allele is dominant

• One allele is recessive

• Both alleles are recessive

• Both alleles are dominant

What is an example of co-dominance in animals?

• A cow with only white fur

• A cow with only black fur

• A cow with both black and white patches

• A cow with mixed fur color

How does co-dominance differ from incomplete dominance?

• Incomplete dominance shows only one trait

• Co-dominance shows both traits distinctly

• Incomplete dominance shows both traits equally

• Co-dominance results in a blend of traits

Which of the following is true about incomplete dominance?

• One trait is completely dominant

• Traits are blended together

• Both traits are equally visible

• Neither trait is expressed

What is the result of mixing colors in incomplete dominance?

• A new color is formed

• No color is visible

• Both original colors are visible

• One color dominates the other
