Neocaridina sibling mating versus unrelated mating

Species, evidence class and date

Neocaridina davidi · Controlled relatedness comparison · 2022

Parents or study design

Inbreeding treatment: females with brothers; outbreeding: females with non-brothers, two broods monitored

Recorded results

Inbreeding did not stop mating or egg fertilization, but fewer hatchlings survived and some starvation/late juvenile performance worsened

Numerical counts and denominator

First and second brood experiments; source abstract does not provide total hatchlings by grade

Claims requiring caution

None

Important limitations

Potential inbreeding depression after one generation; do not derive color-line dominance or apply findings quantitatively to Caridina.
