Genetics of Jellyfish and Flowers

The video tutorial explains incomplete dominance in genetics, using examples like flower and jellyfish color mixing. It covers how dominant genes from parents result in a new phenotype, such as purple flowers from red and blue parents. The tutorial also differentiates between codominance and incomplete dominance, emphasizing the importance of understanding phenotypes in genetic problems.

What is the result when red and blue flowers are crossed in incomplete dominance?

• Red flowers

• Blue flowers

• Purple flowers

• Green flowers

In SpongeBob's flower example, what is the genotype for purple flowers?

• Big R Big R

• Big B Big B

• Big R Big P

• Big P Big P

What percentage of offspring would be purple when crossing red and blue flowers?

• 100%

• 75%

• 50%

• 0%

What color results from crossing yellow and blue jellyfish?

• Blue

• Yellow

• Purple

• Green

What is the genotype for a goober jellyfish?

• YY

• BB

• RR

• BY

What percentage of offspring would be yellow when crossing a yellow and a goober jellyfish?

• 100%

• 50%

• 25%

• 0%

In incomplete dominance, what does a new phenotype indicate?

• Recessive trait

• Dominant trait

• Codominance

• Incomplete dominance

What is the key difference between codominance and incomplete dominance?

• Both traits are invisible in incomplete dominance

• A new trait is visible in incomplete dominance

• A new trait is visible in codominance

• Both traits are visible in codominance

What is the phenotype of offspring when both parent traits are visible?

• Codominance

• Recessive

• Incomplete dominance

• Dominant

What should you look for to identify incomplete dominance in a phenotype?

• One trait visible

• No traits visible

• Both traits visible

• New trait visible
