Answer:
Gender bias is the tendency to prefer one gender over another. It is a form of unconscious bias, or implicit bias, which occurs when one individual unconsciously attributes certain attitudes and stereotypes to another person or group of people.
Example:
An example of second-generation gender bias is that leaders are expected to be assertive, so that women who act in a more collaborative fashion are not viewed as leaders, but women who do act assertively are often perceived as too aggressive. This kind of bias, or gender stereotyping, can be entirely unconscious.
