🤓 Based on our data, we think this question is relevant for Professor Dhameja's class at SCAR.

Solution: When imbalances occur in the sex ratio of sexual species that have two sexes (i.e., other than a 50:50 ratio), the members of the minority sex often receive a greater proportion of care and resources from parents than do the offspring of the majority sex. This is most clearly an example of _______ selection.a. frequency-dependentb. sexualc. disruptived. balancinge. stabilizing
