Selective Breeding Review

Front

What is selective breeding?

Back

Selective breeding is the process of choosing specific organisms with desirable traits to mate, in order to produce offspring with those traits.

What is the purpose of selective breeding in agriculture?

Back

The purpose of selective breeding in agriculture is to enhance desirable traits in crops and livestock, such as increased yield, disease resistance, or better quality.

Front

What is natural selection?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is the difference between selective breeding and natural selection?

Back

Selective breeding is a human-directed process to enhance specific traits, while natural selection is an environmental process that occurs without human intervention.

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, represented by the alleles it possesses.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

What does it mean for a trait to be dominant?

Back

A dominant trait is one that will express itself in the phenotype even if only one copy of the allele is present.

Front

What does it mean for a trait to be recessive?

Back

A recessive trait is one that will only express itself in the phenotype if two copies of the allele are present.

Front

What is an example of a trait that has been enhanced through selective breeding?

Back

An example is the development of larger, seedless watermelons through selective breeding.

Front

What is the role of pollinators in natural selection?

Back

Pollinators help plants reproduce by transferring pollen, which can lead to the selection of plants with traits that attract these pollinators.
