Answer:

Step-by-step explanation:

Depression does not have a clear pattern of inheritance in families. People who have a first-degree relative (for example, a parent or sibling) with depression appear to have a two to three times greater risk of developing the condition than the general public

Genetics may play a role in how likely you are to get depression or anxiety. But they're not the whole story. If someone in your family has either or both of these conditions, you're more likely to, as well. But it doesn't mean you definitely will.

In an older twin study, the heritability of women was also higher than that of men, although no statistically significant (Jansson et al., 2004). Scourfield et al. (2003) show higher heritability for young girls (children) than young boys only from parent-rated depressive symptoms, not self-rated depressive symptoms
