Types of Inheritance

What is a genotype?

• The physical appearance of an individual.

• The genetic constitution of an individual, represented by the alleles inherited from parents.

• The environmental factors affecting an individual's traits.

• The process of cell division in organisms.

What is incomplete dominance?

• A genetic situation where one allele completely masks the effect of another allele.

• A genetic situation in which one allele does not completely dominate another allele, resulting in a phenotype that is a blend of the two traits.

• A genetic situation where both alleles are expressed equally in the phenotype.

• A genetic situation that only occurs in sex-linked traits.

What is the phenotype of heterozygous chickens (black and white feather alleles) due to codominance?

• Solid black feathers.

• Solid white feathers.

• Speckled black and white feathers.

• Striped black and white feathers.

What color flowers result from crossing a red flower (RR) with a white flower (WW) in incomplete dominance?

• Red (RR) flowers.

• White (WW) flowers.

• Pink (RW) flowers.

• Purple (RP) flowers.

What is the genotype of a homozygous dominant individual?

• AA

• Aa

• aa

• AB

Which genotypes are considered dominant?

• AA

• Aa

• BB

• Aa and AA

What is codominance?

• A genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that shows both traits.

• A genetic scenario where one allele completely masks the effect of another allele.

• A genetic scenario where neither allele is dominant, resulting in a blended phenotype.

• A genetic scenario where traits are inherited independently of each other.

What is the difference between codominance and incomplete dominance?

• In codominance, both traits are fully expressed, while in incomplete dominance, the traits blend.

• Codominance results in a mix of traits, while incomplete dominance shows one trait only.

• Codominance is when one trait is dominant over another, while incomplete dominance is when traits are completely separate.

• In codominance, traits are not expressed at all, while in incomplete dominance, traits are expressed partially.

What color fur does a calico cat have?

• Black and white

• Orange and black

• Gray and white

• Brown and cream

What is a phenotype?

• The genetic makeup of an organism.

• The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences.

• The process by which traits are passed from parents to offspring.

• The study of how organisms interact with their environment.
