Genetics: Probability and Inheritance

The video explains the concept of incomplete dominance in genetics, using examples of bunnies and flowers. It describes how neither allele is completely dominant, resulting in a blended phenotype. The video also covers Punnett squares and provides practice problems to reinforce the concept.

What is the main focus of the video tutorial?

• Autosomal recessive inheritance

• Complete dominance

• Incomplete dominance

• Co-dominance

In the story of Flippy and Floppy, what color are the hybrid offspring?

• Gray

• Black

• Brown

• White

What is the probability of Flippy and Floppy having a gray offspring?

• 25%

• 50%

• 75%

• 100%

What is the genotype of a heterozygous individual in the bunny example?

• BW

• WB

• BB

• WW

In the example with carnations, what color results from crossing a red and a white flower?

• White

• Pink

• Red

• Yellow

What is the genotype of a pink carnation in the example provided?

• WW

• RW

• YY

• RR

How does co-dominance differ from incomplete dominance?

• Co-dominance results in a blend of traits.

• Co-dominance is the same as incomplete dominance.

• Co-dominance shows both traits distinctly.

• Co-dominance only shows one dominant trait.

In the example of co-dominance, what is observed in the flower petals?

• A blend of colors

• Only red petals

• Only white petals

• Distinct patches of red and white

What is the probability of obtaining a yellow fish in the practice problem?

• 50%

• 25%

• 75%

• 0%

In the practice problem with flowers, what is the probability of growing a pink flower?

• 75%

• 50%

• 25%

• 100%
