The anlage of the fetus' heart was coming along nicely.

An anlage is a primordium, the initial clustering of embryonic cells from which a body part develops.

Rudolf Ortner has written:

'Sportbauten, Anlage, Bau, Ausstattung'

In "The Grapes of Wrath," the term "anlage" refers to inherited potential or predisposition found within individuals. Each character in the novel possesses their own unique anlage, whether it be a strength, weakness, skill, or flaw that shapes their actions and interactions with others as they navigate the challenges of life during the Great Depression. These inherent qualities influence the characters' development throughout the book, reflecting their resilience, compassion, or struggles in the face of adversity.
