Natural Selection

Greater disease resistance as faster metabolism aids rapid immune response development against pathogens.

Increased greenhouse gas emissions from heightened respiration contributing further toward climate change.

Improved nutrient absorption and utilization resulting in better overall health and productivity.

Enhanced fertility and reproductive capacity leading to increased population growth.

By choosing individuals expressing certain traits to reproduce more often than others.

By introducing mutations that cause new coat colors at random.

By reducing genetic diversity so that only one coat color is present in all dogs.

By allowing natural selection to determine which traits are passed on.

loss of genetic diversity in a population

emergence of new species

adaptation of a population to changing environmental conditions

development of new and useful traits in a population

Artificial selection is directed by human choices, while natural selection is driven by environmental factors.

Artificial selection is random, while natural selection is directed.

Artificial selection occurs in wild populations, while natural selection occurs in domesticated populations.

Artificial selection is driven by genetic drift, while natural selection is directed by gene flow.

The trait skips generations and reappears in the next.

Two affected parents have an unaffected child.

The trait appears in every generation.

The trait is more common in males than females.

To selectively breed cows that produce milk with high butterfat content to enrich the taste and quality of the product.

To breed cows that are more tolerant of temperatures to reduce costs.

To change the body shape of cows to improve feed efficiency and convert grass into milk more efficiently.

To increase resistance to diseases and decrease mortality among the herds.

It can only be done in controlled laboratory settings.

It can introduce new traits that are maladaptive in certain environments.

It can lead to the evolution of new species.

It can reduce genetic diversity within a population.

In natural selection, humans choose which individuals will reproduce based on having desirable traits.

Artificial selection involves intentional breeding while natural selection involves selective environmental pressures.

Natural selection involves intentional breeding while artificial selection involves selective environmental pressures.

Artificial selection takes place in a natural environment, unlike natural selection.

Offspring are less likely inheriting deleterious genes since breeders are selecting against them actively.

Dogs' lifespans increase because breeders also select for longevity while focusing on aesthetic traits.

Physical traits such as speed and agility may improve alongside aesthetic traits due to linked genes.

Breeding for these physical features can result in inherited health issues like breathing problems or dermatitis.

Through random mating without any preference or intervention from humans

By deliberately selecting for desirable traits over several generations

Solely by allowing survival of the fittest without human intervention

By introducing new genetic material using transposons only
