cancellous
spongy
cortical
epiphysis

question 25 (2 points)
traits with two or more genes influencing phenotype and an environmental component are called...
simple
multifactorial
pleiotropic
anthropometric

Explanation:

Analyze Question 24

The question asks for the dense, outer shell of bone making up the majority of the diaphysis (shaft) of long bones.

• Cancellous and Spongy refer to the porous, inner bone tissue.
• Epiphysis refers to the rounded end of a long bone, not a tissue type.
• Cortical (or compact) bone is the dense outer shell that forms the diaphysis.

Analyze Question 25

The question asks for traits influenced by two or more genes as well as an environmental component.

• Simple traits usually follow basic Mendelian inheritance of single genes.
• Pleiotropic refers to a single gene affecting multiple phenotypic traits.
• Anthropometric refers to physical measurements of the human body.
• Multifactorial traits are those influenced by multiple genes (polygenic) combined with environmental factors.

Answer:

Question 24

• Cancellous
• Spongy
• Cortical (Correct answer)
• Epiphysis

Question 25

• Simple
• Multifactorial (Correct answer)
• Pleiotropic
• Anthropometric
