involving, relating to, or derived genetically from, one parent only
a uniparental chromosome
We wanted to understand what the costs and benefits of biparental versus uniparentalcare were in these birds.
uniparental in American English

adjective
Biology
having one parent, as an organism produced by parthenogenesis
Derived forms
uniparentally
adverb
Word origin
[1895–1900; uni- + parental]This word is first recorded in the period 1895–1900. Other words that entered Englishat around the same time include: Marxism, backwind, cutback, freewheel, neonuni- is a combining form occurring in loanwords from Latin (universe), used, with the meaning “one,” in the formation of compound words (unicycle). Other words that use the affix uni- include: uniaxial, unicycle, uniform, unipolar, unison

Our data thus reveal the potential for a flexible switch from biparental to uniparental care.
