Understanding Inheritance Patterns

What is a key characteristic of non-Mendelian inheritance patterns?

• They always follow Mendel's laws.

• They involve only one type of allele.

• They do not follow Mendel's laws of inheritance.

• They result in only one phenotype.

In a cross between red and white flowers showing incomplete dominance, what is the resulting phenotype?

• Speckled

• White

• Red

• Pink

What is the probability of getting a pink flower from a cross between two pink flowers?

• 25%

• 100%

• 50%

• 75%

In a cross between two pink flowers, what is the probability of getting a white flower?

• 25%

• 0%

• 75%

• 50%

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

• Neither allele is expressed.

• Both alleles are expressed together.

• One allele is dominant.

• Only recessive alleles are expressed.

What is the phenotype of offspring in a co-dominance cross between red and white flowers?

• Speckled

• White

• Pink

• Red

What is an example of co-dominance in animals?

• Black and white chickens resulting in black chickens.

• Black and white chickens resulting in white chickens.

• Black and white chickens resulting in speckled chickens.

• Black and white chickens resulting in gray chickens.

How can non-Mendelian inheritance patterns benefit agriculture?

• By reducing the number of plant species.

• By improving plant and livestock breeds.

• By eliminating genetic diversity.

• By increasing the number of recessive traits.

What is the main difference between incomplete dominance and co-dominance?

• Incomplete dominance results in a new phenotype, while co-dominance shows both parent phenotypes.

• Incomplete dominance shows both parent phenotypes, while co-dominance results in a new phenotype.

• Both incomplete dominance and co-dominance result in a new phenotype.

• Neither incomplete dominance nor co-dominance show parent phenotypes.

What is the purpose of the practice exercise at the end of the video?

• To understand the history of genetics.

• To determine the pattern of inheritance in given crosses.

• To memorize Mendel's laws.

• To learn about plant growth.
