Examine the following figure and answer the following questions.
What characteristics are shared by the mammalian clade and the primate clade? What characteristic distinguishes the primates from other members of the mammalian clade?
Verified step by step guidance1
Examine Figure 1.17 to identify the shared characteristics of the mammalian clade. Mammals typically share traits such as the presence of mammary glands, hair or fur, and endothermy (warm-bloodedness).
Next, identify the shared characteristics of the primate clade. Primates generally share traits such as forward-facing eyes, a large brain relative to body size, and grasping hands with opposable thumbs.
Compare the traits of the mammalian clade and the primate clade to determine which characteristics are shared by both groups. These shared traits will represent the common features of primates as mammals.
Identify the distinguishing characteristic(s) of primates that set them apart from other mammals. Look for unique traits in the primate clade that are not present in the broader mammalian clade.
Summarize your findings by listing the shared characteristics of the mammalian and primate clades, as well as the unique characteristic(s) that distinguish primates from other mammals.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Mammalian Clade Characteristics
The mammalian clade is characterized by features such as warm-bloodedness, hair or fur, and mammary glands that produce milk for offspring. These traits are essential for the survival and nurturing of young mammals, allowing them to thrive in various environments. Understanding these characteristics helps in identifying the broader traits shared among all mammals.

Primate Clade Characteristics
Primates, a subgroup within the mammalian clade, exhibit unique characteristics such as flexible limb structure, enhanced vision, and larger brain-to-body size ratios. These adaptations facilitate complex behaviors and social structures. Recognizing these traits is crucial for distinguishing primates from other mammals and understanding their evolutionary significance.

Evolutionary Distinction
The evolutionary distinction between primates and other mammals often centers on traits like opposable thumbs and advanced cognitive abilities. These features enable primates to manipulate objects and engage in problem-solving, setting them apart from other mammalian groups. This distinction is vital for understanding the evolutionary pathways that led to the diverse behaviors and adaptations seen in primates today.

Textbook Question
Suppose a genotype for a protein-producing gene can have any combination of three alleles, A₁, A₂, and A₃.
Each allele produces a protein with a distinct electrophoretic mobility. Allele A₁ has the highest electrophoretic mobility, A₃ has the lowest electrophoretic mobility, and the electrophoretic mobility of A₂ is intermediate between them. Draw the appearance of gel electrophoresis protein bands for each of the possible genotypes. Be sure to label each lane of the gel with the corresponding genotype.
