Inherited and Acquired Traits Practice

Which of the following are examples of polygenic inherited traits?

• Skin color, intelligence, and height

• Favorite cuisine, dialect spoken, and leisure activities

• Fashion sense, musical taste, and athletic abilities

• Academic achievement, job selection, and ideological beliefs

Identify which of the following traits are not inherited genetically but are developed through environmental influences and personal experiences:

• Eye color, height, and blood type

• Language proficiency, enhanced muscle strength from regular training, and suntan acquired from sun exposure

• Number of limbs, type of blood cells, and genetic disorders

• Hair color, skin color, and innate musical talent

Which of the following best describes the concept of inherited traits in the context of genetics?

• Genetic characteristics transmitted from parents to their progeny through DNA

• Attributes acquired by an organism during its lifetime due to environmental influences

• Behaviors that are learned and adapted from the surrounding environment

• Abilities honed and perfected through repeated practice and experience

Which of the following best describes acquired traits in the context of evolutionary biology?

• Traits that are genetically inherited from one's ancestors

• Traits that emerge as a result of environmental influences and life experiences

• Traits that are present from the moment of conception

• Traits that are consistently passed down through generations

Analyze and explain two genetic adaptations of polar bears that enable them to thrive in Arctic environments.

• White fur for camouflage and a thick layer of skin/fat to stay warm in cold weather.

• Sharp claws and strong legs for hunting and swimming.

• Keen sense of smell and excellent night vision.

• Ability to hibernate and store food for winter.

Which of the following are inherited traits that enhance a frog's survival in its natural habitat?

Which of the following scenarios best illustrates the concept of acquired traits in humans, as opposed to inherited traits?

• Receiving genetic traits such as eye color and blood type from one's parents.

• Possessing an innate ability for mathematics and being naturally tall due to genetic factors.

• Having the ability to metabolize lactose and inheriting a specific blood type.

Which of the following best describes the function of genes within an organism's genome?

• A segment of DNA that encodes the information necessary for the synthesis of proteins, influencing specific traits.

• A type of protein that regulates cell functions and maintains homeostasis.

• A type of cell that forms the structure of tissues and organs.

• A chemical compound that provides energy to cellular processes.

Which of the following traits is most likely to be influenced by environmental factors rather than genetic inheritance?

• Eye color

• Height

• Ability to play a musical instrument

• Blood type
