Selective Breeding Quiz - Cognito

What is selective breeding?

• Breeding only the best individuals in a population

• Breeding all individuals in a population

• Breeding individuals randomly

• Breeding individuals with the worst traits

How long have humans been using selective breeding?

• 100 years

• 1000 years

• 1,000,000 years

• 10,000 years

What is the main purpose of selective breeding?

• To reduce the gene pool of the population

• To increase inbreeding

• To get better offspring with desired traits

• To decrease the variation within the population

What is a drawback of selective breeding?

• It has no drawbacks

• It leads to less variation within the population

• It increases the gene pool of the population

• It reduces the gene pool of the population

What is the gene pool of a population?

• The collection of all the different alleles held by an entire population

• The number of individuals in a population

• The total area occupied by a population

• The number of genes in a population

What can inbreeding lead to?

• Increased susceptibility to diseases and inherited defects

• Decreased health conditions

• Increased resistance to diseases

• Decreased inherited defects

Why are dogs like german shepherds and rottweilers prone to health conditions?

• Because they have a large gene pool

• Because they have a small gene pool

• Because they have no gene pool

• Because they have high variation within the population

What is a potential risk of having a small gene pool in a population of plants?

• Decreased variation within the population

• Increased variation within the population

• Decreased susceptibility to diseases

• Increased resistance to pathogens
