Morphology

unilateral + descent

The noun phrase is compositionally clear: 'unilateral' means one-sided or from one side, and 'descent' means lineage or ancestry, so the combined meaning is lineage traced through one side/parent. This adjective+noun pattern is regular and cross-linguistically familiar, so a B1 learner who knows both constituents should be able to infer the intended anthropological sense.

Etymology

Unilateral descent is like choosing one family tree to follow — imagine you only trace your mother's branch or only your father's branch. Because unilateral means 'one-sided' and descent means 'family line', the term refers to tracing a person's family through only one parent's line.
